DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(11) FIG. 1 shows the basic construction of an ultrasonic processing device 1. The ultrasonic processing device 1 comprises an ultrasonic generator 10, a converter 22, a booster 24, a linearly movable sonotrode 26, a roll or an anvil 30, respectively, as counter tool as well as a gap 29 formed between the sonotrode 26 and the roll 30.

(12) By analogy to the above described construction of the ultrasonic processing device 1, it is also preferred to provide a rotatable sonotrode (not shown). Therein, at least one sonotrode is arranged within a roll. The sonotrode roll is beared or supported rotatably around a central axis. A circumferential area of the sonotrode roll comprises the function of the circumferential surface of the roll 30 described in detail below. To be able to adjust the gap between the rotating sonotrode roll and the oppositely arranged anvil, the sonotrode roll and/or the anvil (not shown) are linearly movable. The relative movement resulting from this movement between sonotrode roll and anvil ensures a specific adjustment of a width of the gap between rotating sonotrode and anvil.

(13) In the following, the preferred construction, function and processing method of the ultrasonic processing device are described with respect to the ultrasonic processing device 1 depicted in the accompanying drawings. These explanations apply in the same way to the not-shown ultrasonic processing devices comprising for example a rotating sonotrode roll and an anvil.

(14) The ultrasonic generator 10 creates a high-frequent electric oscillation from the supplied electrical energy or the electrical supply voltage U.sub.N. The high frequent electrical oscillation or energy, respectively, is transformed in the converter or sound transducer 22 into a mechanical oscillation. The mechanical oscillation of the converter 22 is preferably amplified by the booster 24 and then transmitted to the sonotrode 26. Oppositely to the sonotrode 26, the rotatable roll 30 or the anvil, respectively, is arranged as counter tool so that the sonotrode 26 and the roll 30 are spaced from each other by the gap 29. Due to the rotatable arrangement of the roll 30, a web material 40 (not shown in FIG. 1) to be processed is moved through the gap 29 and is processed thereby by means of ultrasonics. The ultrasonic energy is introduced into the web material 40 via the sonotrode 26.

(15) During the processing process, preferably an angular speed of the roll 30 is detected by an angular speed sensor 38 (step I). To be able to adjust the gap 29 and the ultrasonic processing device 1 to the web material 40, the position of the sonotrode 26 relative to the roll 30 is adjustable via an actuator 28 with position sensor or manually. Instead of an electric actuator 28 or linear motor, also a hydraulically or pneumatically operated actuator is preferred.

(16) Resulting from the above description, by means of the ultrasonic processing device 1, different processing processes are realizable as for example the known ultrasonic welding, the ultrasonic cutting and the ultrasonic sewing. In the following, ultrasonic processing processes are described which are based in general on the example of the ultrasonic welding.

(17) The FIGS. 2 and 3 show schematically different preferred configurations of the roll 30. FIG. 2 illustrates a roll having an even circumferential surface 32. By means of the even circumferential surface 32, an even processing pattern, preferably a welding pattern, is created on a first material web 40. The material web 40 consists, according to a preferred embodiment of the present invention, of a plurality of material layers arranged above each other. A thus processed material web 40 is also called a constant welding application or in general, constant or continuous processing application. Such continuous welding applications are also called surface welding with non-interrupted welding contours. The surface occupancy of the roll 30 or the welding power, respectively, is constant over the complete welding contour for one revolution of the roll 30.

(18) FIG. 3 illustrates a roll 30 having an uneven circumferential surface 34. On the uneven circumferential surface 34, at least one detectable contour 36, 37 is provided, which is formed in an elevated way with respect to adjacent roll portions 35. The detectable contour 36, 37 protrudes in the direction of the sonotrode 26 from the uneven circumferential surface 34 and periodically constricts the gap 29 during the rotation of the roll 30. Preferably, the contour 36, 37 extends transversely to the circumferential direction of the roll and is thus also called transverse contour 36, 37. By means of the rotation of the roll 30, the material layer of the web materials 40 arranged above each other is preferably welded in the area of the contours 36, 37 so that so-called transverse seams 42, 43 are created in the web material 40. The contours 36, 37 may also extend in an angle distinct from 90 with respect to the circumferential direction of the roll 30. Further, it is preferred to provide also the contours 36, 37 continuously or discontinuously, which means in constant or varying height. As such contours 36, 37 are also used for welding curved patterns, seam courses and surfaces as for example for producing gloves from web material, the contours 36, 37 have arbitrary courses with respect to the circumferential direction of the roll 30 with arbitrary elevation levels. Accordingly, the term contour means these arbitrary courses of roll elevations and the term transverse seam means the seams created by means of these arbitrary contours.

(19) Between these transverse seams 42, 43 of the welded material web, the portions 44 are arranged. In the portion 44, the web material is welded differently, for example less or not at all, compared to the portion of the transverse seams 42, 43. From this it follows that at an uneven welding contour 36 of the roll 30, the surface occupancy of the roll and thus the welding power varies over one revolution of the roll. At the same time, the surface occupancy of the roll is completely processed by one revolution of the roll and the respective welding pattern is impressed into the web material 40 (see FIG. 3). Due to the rotatory constructed ultrasonic processing device 1 with the rotating roll 30, the repeatability of the processing processes between the sonotrode 26 and the roll 30 is given, wherein these processing processes are detectable (see below).

(20) In the ultrasonic generator 10, the electric energy is transformed into a high-frequent electrical oscillation. For this purpose, the ultrasonic generator 10 comprises an analog power unit 12. Further, from this power unit 12, a plurality of generator data is detectable via a signal detection 14. The generator data comprises all or a selection of the following data sets: electrical ultrasonic voltage U.sub.us, electrical ultrasonic current I, amplitude actual value A.sub.ist of the ultrasonic oscillation and ultrasonic generator power actual value P.sub.ist.

(21) The ultrasonic generator 10 also comprises an internal signal processing 16, preferably a digital signal processing by means of which at least a selection of the generator data is processible. The signal processing 16 comprises a system time or clock, respectively, like every common PC or industry computer so that the system time is available as reference signal of the signal processing 16. Until now, the signal processing 16 was used among others for controlling and/or regulating the frequency of the ultrasonic signal. For example, a controlling electronic and a controlling software was used for regulating the ultrasonic frequency to the resonance frequency of the ultrasonic processing device. By means of the signal detection 14 and the signal processing 16, the generator data is detectable depending on the time and can be evaluated. This evaluation, which does not necessarily require a depiction, is illustrated in a qualitative way for an ultrasonic welding method with a roll 30 having an uneven circumferential surface 34 in FIG. 4. The rotation of the roll 30 with one or a plurality of contours 36, 37, here preferably two transverse contours, creates in the generator data timely periodically repeating peaks P.sub.36 and P.sub.37. From each revolution of the roll 30, a peak P.sub.36, P.sub.37 per contour 36, 37 results. Thus, the timely distance between two similar peaks P.sub.36 or P.sub.37 signalizes one complete revolution U of the roll 30. In case the transverse contour is moved past the sonotrode 26 and reduces the gap 29, an ultrasonic processing, preferably an ultrasonic welding of the web material, occurs in the area of the transverse contour 36. In this timely range, which is periodically repeated with each revolution U of the roll 30, the ultrasonic amplitude A is temporarily decreased. At the same time, the ultrasonic frequency F, the ultrasonic current I and the ultrasonic generator power P increase as can be seen based on the positive and negative peaks in FIG. 4. The ultrasonic voltage U.sub.us also shows a signal variation in the timely processing range of the transverse contour 36 which recognizably returns timely periodically. Thus, the data detected depending on the time shows typical and timely periodically repeating patterns in the timely portions of the ultrasonic processing of the material web 40 by means of the uneven circumferential surface 34 of the roll 30 of the ultrasonic processing device 1. These repeating patterns have preferably the shape of positive or negative peaks or of characteristic variations plotted over the time. These patterns are automatically detectable by means of a filter (not shown) or another suitable evaluation electronic. Based thereon, preferably the time point or the time range of the respective pattern and the timely distance between direct and multiple sequenced similar and non-similar patterns are determinable. Similar patterns describe a signal variation of the same physical quantity, as for example the ultrasonic voltage U.sub.us, caused by the same contour 36 or 37. Non-similar patterns describe signal variations of the same physical quantity but caused by different contours 36; 37 on the roll 30.

(22) Thus, from one or a plurality of data sets of the generator data, it is recognizable when and over which time range web material is processed in the gap 29. Further, from the timely distance of two similar peaks or patterns, for example P.sub.36 or P.sub.36 it is recognizable in which time one revolution U of the roll 30 is completed. On this basis, preferably a controlling/regulating module 50 (see below) or the signal processing 16 determines the present angular speed of the roll 30 from the timely distance of two subsequent similar patterns which have been caused by the same transverse contour 36; 37 (step II). Especially, an angular segment of 360 is divided by the predetermined timely distance. It is also preferred to divide the number of the detected revolutions U by the time required therefore to get the rotation speed of the roll 30 for usage in the further preferred processing steps. It is further preferred to determine the timely distance of two subsequent and non-similar patterns which have been caused by different transverse contours 36, 37 as the construction of the roll 30 and thus also the angular segment between the transverse contours 36, 37 is known, also the angular speed of the roll 30 is determinable from the quotient of the angular segment between the transverse contours 36, 37 and the sensed timely distance.

(23) The ultrasonic generator 10 comprises further the controlling/regulating module 50 which is integrated into the signal processing 16 of the ultrasonic generator 10. Preferably, the signal processing 16 and the controlling/regulating module 50 are realized digitally. Indeed, at a preferred analog power unit 12, an analog-digital (A/D) transducer for transmitting the detected analog generator data to the digital signal processing 16 and to the controlling/regulating module 50 is necessary but overall, the digital implementation of the signal processing 16 and the controlling/regulating module 50 realizes a faster data processing compared to known systems.

(24) A further advantage of the integration of the controlling/regulating module into the signal processing 16 of the ultrasonic generator 10 consists in that preferably all or a selection of generator data is available for the controlling/regulating module 50 in real time without a long transmitting path and the time losses connected therewith. This realizes a faster and more precise regulating process and thus more constant and better ultrasonic welding connections compared to the prior art. Preferably, the signal detection 14 detects and transmits a selection or all of the above-mentioned generator data of the ultrasonic generator 10 within a time range of 1 to 100 s, preferably in less than 80 s and further preferred in less than 50 s to the signal processing 16 and especially to the controlling/regulating module 50 with the gap regulator 60 and the amplitude regulator 70 (see above). In known systems, generator data is provided to an external controller. The transmitting of the generator data takes place partly via a plurality or several A/D (analog/digital) and D/A (digital/analog) transducers with transducing times of up to 10 ms. In the controller of the prior art, which is external of the ultrasonic generator, data processing processes were realized in the range of 5 to 50 ms. The subsequent transmitting of the controlling signals, for example for positioning the sonotrode, required further 5 to 10 ms. In sum, disadvantageous reaction times of individual components as well as the whole ultrasonic processing device of the prior art result so that a reaction to undesired processing situations could be realized only slowly compared to the present invention.

(25) FIG. 5 shows a schematic block diagram of a preferred embodiment of the ultrasonic processing device 1. The ultrasonic processing device 1 operates with a roll 30 having an even circumferential surface 32 (see above). Further, the roll 30 is provided with the angular speed sensor 38 detecting the angular speed of the roll 30 and transmitting it to the integrated controlling/regulating module 50. Further, the ultrasonic processing device 1, here preferably an ultrasonic welding device, comprises the actuator 28 with position sensor for adjusting the sonotrode position and thus the width of the gap 29. The actuator 28 is connected to a position regulator 27 receiving a reference position POS.sub.soll of the sonotrode 26 from the controlling/regulating module 50 and adjusting this reference position POS.sub.soll by means of the actuator 28.

(26) The integrated controlling/regulating module 50 comprises a gap regulator 60 and an amplitude regulator 70 comprising preferably a PID-regulator. Both regulators 60, 70 serve the regulating of the energy input into the material web, which is moved through the gap 29 by means of the rotation of the roll 30. The gap regulator 60 and the amplitude regulator 70 are usable preferably alone or in combination. For this purpose, the gap regulator 60 determines a reference position POS.sub.soll of the sonotrode 26 relative to the roll 30 (step III) to adjust a power actual value P.sub.ist of the ultrasonic generator 10 to a predetermined power reference value P.sub.soll of the ultrasonic generator 10. This reference position POS.sub.soll is preferably transmitted via a digital/analog (D/A) transducer or via a field bus to the position regulator 27 of the sonotrode 26. The position regulator 27 regulates then the reference position POS.sub.soll of the sonotrode 26, while it uses the actual position of the sonotrode 26 from the position sensor for a comparison (step IV).

(27) For determining the reference position POS.sub.soll of the sonotrode 26, the gap regulator 60 first receives the angular speed of the roll 30 from the angular speed sensor 38. It is also preferred that the angular speed sensor 38 transmits a reference signal for the angular speed of the roll 30 to the controlling/regulating module 50, which is then transformed by the controlling/regulating module 50 into an angular speed of the roll 30. The determined angular speed of the roll 30 is transmitted to a memory S1 of the gap regulator 60. In the memory S1, a learned characteristic curve and/or a characteristic value chart and/or a plurality of taught characteristic values is saved which specify alone or in combination the reference power P.sub.soll of the ultrasonic generator 10 for the material processed in the gap 29 depending on the angular speed of the roll 30. The reference power P.sub.soll of the ultrasonic generator determined in this way is compared with the currently effective actual power P.sub.ist of the ultrasonic generator 10, which has been transmitted to the gap regulator 60 from the signal detection 14. Preferably, the signal detection 14 transmits the actual power P.sub.ist of the ultrasonic generator 10 within a time range of 1 to 100 s, further preferred in less than 80 s and even more preferred in less than 50 s to the controlling/regulating module 50 with gap regulator 60 and amplitude regulator 70. In the gap regulator 60, a processing of the present data is performed in a preferred time range of 1 to 100 s, preferably in less than 80 s and further preferred in less than 50 s.

(28) The result of this comparison of reference power P.sub.soll and actual power P.sub.ist of the ultrasonic generator 10 in the gap regulator 60 is transferred to the regulator RS1, which accordingly specifies a reference position POS.sub.soll of the sonotrode 26 and thus a width of the gap 26. The reference position POS.sub.soll of the sonotrode is transmitted to the position regulator 27 and realized, whereby the actual power P.sub.ist of the ultrasonic generator 10 is regulated to the reference power P.sub.soll. The transmitting of the reference position POS.sub.soll to the position regulator 27 preferably occurs in a time range of 1 to 10 ms, preferably in less than 5 ms and even more preferred in less than 2 ms. The position regulator 27 realizes the predetermined reference position POS.sub.soll or the gap width, respectively, preferably within 20 to 50 ms, in case it is realized by an electric actuator. In case the position regulator 27 is realized by a pneumatic actuating system according to a further preferred embodiment, the predetermined reference position POS.sub.soll is realized within 50 to 500 ms.

(29) The amplitude regulator 70 specifically changes the amplitude A of the ultrasonic signal. Thereby, and at the fixedly arranged sonotrode 26, the energy input into the web material in gap 29 is specifically increased when the amplitude A is increased or the energy input is decreased in case the amplitude A is decreased. A memory S2 of the amplitude regulator 70 also receives the angular speed of the roll 30 from the angular speed sensor 38 (see above). This occurs in an analogous way with respect to the gap regulator 60. In the memory S2, characteristic curves and/or characteristic value charts and/or taught or learned values, respectively, with respect to the processed web material are recorded for the power of the ultrasonic generator 10 depending on the rotation, especially the angular speed , of the roll 30. By means of the angular speed and the specification of the processed material in the memory S2, a reference value P.sub.soll for the power of the ultrasonic generator 10 can be taken (step V). This reference value P.sub.soll of the generator power is compared to the actual power P.sub.ist of the ultrasonic generator 10 received from the signal detection 14. In the regulator or filter RF2, the result of this comparison is converted into an amplitude reference value A.sub.soll to achieve the desired power input P.sub.soll of the ultrasonic generator into the web material in the gap 29 via the change of the amplitude A of the ultrasonic signal. Preferably, the signal detection 14 transmits the actual power P.sub.ist of the ultrasonic generator 10 within a time range of 1 to 100 s, preferably in less than 80 s and further preferred in less than 50 s to the controlling/regulating module 50 with amplitude regulator 70. In the amplitude regulator 70 a processing of the present data is carried out in a preferred time range of 1 to 100 s, preferably in less than 80 s and further preferred in less than 50 s.

(30) The amplitude reference value A.sub.soll is transmitted to the regulator R.sub.A. Based on a comparison of the amplitude actual value A.sub.ist and the amplitude reference value A.sub.soll, the change of the amplitude A is determined (step VI). According to a preferred embodiment of the present invention, the regulating intervention determined for the amplitude in this way is realized electronically and the respective control signals are transmitted to the power unit 12 (see arrow in the FIGS. 5 to 8). The transmitting to the regulator R.sub.A preferably may be carried out within 1 to 100 s, preferably in less than 80 s and further preferred in less than 50 s. The processing of the reference amplitude A.sub.soll in the regulator R.sub.A for realizing the actual amplitude A.sub.ist at the sonotrode 26 is preferably realized within a time range of 1 to 10 ms, preferably less than 8 ms and even more preferred in less than 5 ms.

(31) It is also preferred to regulate the ultrasonic processing device 1 only by means of the amplitude regulator 70. This preferred embodiment is shown schematically in FIG. 6. It can be seen that the gap regulator 60 was omitted. Correspondingly, the sonotrode 26 can also not be positioned via a position regulator 27. To the contrary, a defined position of the sonotrode 26 or a defined width of the gap 29 between roll 30 and sonotrode 26 is preferably adjusted and held by means of the motor 28 or by means of a similar actuator (see above). Therein, the position of the sonotrode 26 can optionally be detected and controlled by a position sensor. It is also preferred to drive the sonotrode 26 against a mechanical stop so that the position of the sonotrode 26 is fixed. According to another embodiment, the sonotrode 26 is manually adjustable and fixable at a predetermined position. As soon as the sonotrode 26 is arranged at the predetermined position, the actual power P.sub.ist of the ultrasonic generator 10 is regulated to the reference power P.sub.soll of the ultrasonic generator 10 by means of the amplitude regulator 70 according to the above described operation by means of the variation of the amplitude of the ultrasonic oscillation. According to a further preferred embodiment of the ultrasonic processing device 1 (cf. FIG. 7), the internal controlling/regulating module 50 detects the angular speed of the roll 30 from at least one data set of the above described generator data (cf. FIG. 4). The ultrasonic processing device 1 comprises in this case a roll 30 having an uneven circumferential contour 34. Therefore, detectable contours 36, 37 influence the timely course of the generator data (see above). The angular speed is derivable from the timely course of the individual generator data which are shown in FIG. 4. For this purpose, a data set, a selection of data sets or all data sets of the generator data are transmitted to a trigger block TB. In the trigger block TB, the time dependent detected data sets of the generator data according to FIG. 4 are evaluated. The evaluation determines at which time positions positive or negative peaks P.sub.36, P.sub.37 or repeating patterns or signal variations, respectively, are present. Based on common processing speeds of the material web 40 and the angular speeds to of the roll 30 connected therewith, the peaks P.sub.36, P.sub.37 or patterns are repeated preferably 2 to 80 times per second, preferably 2 to 50 times and further preferred 2 to 20 times per second, depending on the specific application. As the roll 30 is rotating for longer processing times of several hours up to several days during the operation with constant revolution, the peaks P.sub.36, P.sub.37 are repeated in regular timely distances. These regular timely distances respectively correspond to one complete revolution U of the roll 30 while the detectable contours 36, 37 of the uneven circumferential contour 32 each passes one time the sonotrode 26. The trigger block TB determines the time range, preferably the time point, at which the detectable contours 36, 37 pass the sonotrode 26. In this time range or at this time point, the material web 40 is processed, preferably welded. The time signal which serves as reference is preferably provided by the system time of the controlling/regulating module 50 or the signal processing 16. Therefore, from the evaluation of the trigger block TB it is known with which timely distance a periodically repeating processing occurs, how long this processing takes and when a processing occurs with respect to the system time, in case the timely positions of the first peaks P.sub.36, P.sub.37 of the detectable contours 36, 37 are known. It follows therefrom that by means of the trigger block TB the information, in which specific time ranges as timely fractional parts or as angular segment or as angular position segment of a revolution U of the roll 30 really only a processing of the material web occurs, is provided to the controlling/regulating module 50.

(32) From the data of the trigger block TB a processing block BB10 determines the angular speed of the roll 30. To this end, preferably the processing block BB10 divides the rotation angle of a revolution, i.e. 360, by the time per revolution U. For increasing the precision, preferably also the rotation angle of several revolutions U can be divided by the time required therefore. The determined angle speed is then transmitted to the amplitude regulator 70 and/or the gap regulator 60. In a further preferred processing block BB20, a respective angular position of the detectable contours 36, 37 is determined. Based on a timely reference position, for example where preferably the detectable contours 36, 37 pass the sonotrode 26 for the first time, the time is measured. By means of the angular speed of the processing block BB10 and the measured time, it is always determinable at which angular position the respective detectable contour 36, 37 is presently located.

(33) The angular position is preferably used in a measurement detection block MB. In known systems, the transmitted generator data is averaged over one revolution U of the roll 30. Therein, a disturbing superposition of the signals at the peaks P.sub.36, P.sub.37 or patternsthus of the signals during the timely processing procedures of the material webby the signals during the non-processing procedures occurthus in case no or only small ultrasonic energy is applied to the material web. As by means of the processing block BB20, it is clearly recognizable and detectable in which time ranges actually a processing of the material web 40 occurs, the measurement detection block MB only determines in these processing time ranges the detected generator data or a selection thereof. In this way, the generator data is not superposed by signal noise in the non-processing time ranges so that a higher precision of the generator data compared to known systems is realizable.

(34) According to a preferred embodiment of the present invention, an average value of the detected and repeated generator data due to the rotation of the roll 30 or a selection thereof is generated in the measurement detection block MB. Therefrom, a higher precision of the evaluated generator data results so that at the same time subsequent regulating or controlling processes can be realized which have a higher precision. Thereby, preferably the actual power P.sub.ist of the ultrasonic generator 10 is more precisely determinable which is then transmitted to the gap regulator 60 and/or the amplitude regulator 70. It is thus preferred to ignore the idle power of the ultrasonic processing device 1 in ranges outside of the contours 36, 37, which increases the precision of the detected power average value. Further, only in the areas of the peaks P.sub.36, P.sub.37, a data evaluation is performed and not over the whole revolution of the roll 30. This reduces the evaluation effort and the computing power related thereto.

(35) Based on the evaluation of the generator data in the controlling/regulating module 50, the data detected via the measurement detection block MB are provided within a time range of 1 to 100 preferably in less than 80 s and further preferred in less than 50 s for the further processing and using. Accordingly, from the preferred combination of the generator data provided by the measurement detection block MB and the gap regulator 60 preferably reaction times of the ultrasonic processing device 1 with a gap regulator 60 result in the timely range of 20 to 60 ms with servomotor and of 50 to 500 ms with a pneumatic actuator system. For the preferred combination of the generator data provided by the measurement detection block MB with the amplitude regulator 70, preferably reaction times of the ultrasonic processing device in the range of 1 to 10 ms, preferably less than 8 ms and further preferred of less than 5 ms result.

(36) Further, preferably the angular speeds and the angular position are transmitted to the blocks VSP and VSA. In block VSP a pre-controlling for determining the reference position POS.sub.soll of the sonotrode 26 occurs. In block VSA, a pre-controlling for determining the reference amplitude A.sub.soll of the ultrasonic signal occurs. The function pre-controlling adds to one or different correcting variables of the ultrasonic processing device 1, like preferably the reference amplitude A.sub.soll (step VIII) and/or the reference position POS.sub.soll (step VII) of the sonotrode 26, pre-control values for predictively influencing the ultrasonic processing process for an improved quality and/or reliability. The pre-control values for the reference position POS.sub.soll are recorded in block VSP and the pre-control values for the reference amplitude A.sub.soll are recorded in block VSA. As the ultrasonic processing device is a rotating system and thus has a periodically repeating processing process with each revolution of the roll 30, the pre-control values are preferably recorded as function of the angular position of the roll 30. This is also preferably a linear or a non-linear mathematic function which can be formulated depending on the parameters angular speed and/or rotation angle p. According to a further preferred embodiment of the present invention, the pre-control values are recorded in form of a characteristic line or in form of a characteristic field. Preferably, the characteristic field depends on the angular position and the angular speed of the roll 30. It is also preferred to record this characteristic field parameterized and/or to teach it to the blocks VSA and VSP during the operation of the ultrasonic processing device 1.

(37) Based on the recorded pre-control values as function or characteristic fields, the function of the pre-control values is calculated and/or the characteristic field or the characteristic fields are read depending on the angular position and/or the angular speed w of the roll 30 during the operation of the ultrasonic processing device. The present pre-control values are then impressed to the respective actuator, here the position regulator 60 and the amplitude regulator 70, as shown in FIGS. 7 and 8. To be able to integrate the pre-control values into the timely sequence of the regulating of the ultrasonic processing device 1, a respective computing power is necessary which is ensured by the ultrasonic generator 1 and the integrated controlling/regulating module 50.

(38) It is further preferred that the controlling/regulating module 50 of the ultrasonic generator 10 ensures short cycle times for reading the characteristic field or for calculating the function adapted to the ultrasonic processing. This ensures that the characteristic field is read accordingly often per revolution of the roll 30 and/or the function can be calculated respectively often per revolution of the roll 30. In this manner, the ultrasonic processing procedure can be optimized and a better precision and quality compared to the prior art is realizable. According to a preferred embodiment of the present invention, a pre-controlling takes place with a precision of 10.sup.1o of the rotation angle of the roll 30. In case a complete revolution of the roll 30 takes 200 ms, a cycle time of the blocks VSA and VSP for calculating the function and/or for reading the characteristic field of a maximum of 55 s results. Correspondingly, other precisions are adjustable.

(39) For accelerating the determination of the pre-control values, it is preferred that the pre-control function and the characteristic field are parameterized. This means that the function and the values of the characteristic field are each defined as mathematic terms, respectively, which depend on the parameters angular position and/or the angular speed of the roll 30.

(40) The pre-control has a proactive or predictive influence, respectively, which is used preferably at the ultrasonic welding of subsequent transverse seams. By means of the pre-control, it is acted against the negative reaction force of the web material, which was discussed initially, and against the evasive movement of the sonotrode 26 related thereto. Due to the evasive movement, the gap 29 is opened to such an extent that the seam following a preceding seam does not get a suitable ultrasonic welding and has therefore not the desired strength. The pre-control determines a correction of the reference position POS.sub.soll and/or the reference amplitude A.sub.soll for the angular position at which the transverse contour 37 for producing the subsequent seam is present. Referring to the specific example of the evasive movement, the gap 29 is reduced due to the pre-control of the reference position POS.sub.soll and/or the amplitude of the ultrasonic oscillation is increased due to the pre-control of the reference amplitude A.sub.soll. Thereby, the subsequent seam is producible with satisfying strength. It is also preferred to eliminate other disturbances in the ultrasonic processing in this manner.

(41) FIG. 8 schematically shows a further preferred embodiment of the ultrasonic processing device 1. Here, the gap regulator 60 is omitted. Instead of this, the sonotrode 26 is manually adjusted or by means of an actuator 28 to a predetermined position and is retained there. Accordingly, a defined gap 29 is present through which the material web is moved. The power depending regulating of the ultrasonic generator 10 and thus the ultrasonic processing device 1 is realized by means of the amplitude regulator 70 as it was described above. The required condition data for the regulating or controlling by the amplitude regulator 70 is received from the trigger block TB in combination with the processing block BB10. For increasing the precision of the amplitude regulating 70, it is also preferred to supply the amplitude regulating 70 with a selection of the determined data of the measurement detection block MB. Therefore, and according to a preferred embodiment of FIG. 8, the actual power P.sub.ist of the ultrasonic generator 10 determined by the average block MB is transmitted to the amplitude regulating 70. Further, it is preferred to combine the above described pre-control with the block VSA with the amplitude regulator 70.
