BRIEF DESCRIPTION OF THE FIGURES

(1) In the drawings there are shown

(2) FIG. 1 a paper processing device in schematic lateral view and

(3) FIG. 2 a rolling arrangement of a paper processing device in schematic lateral view.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

(4) A schematic illustration of a paper processing device 1 can be seen from FIG. 1. The paper processing device 1 comprises several paper processing stations. Paper processing measures take place in each of the stations.

(5) A paper supply 2 is arranged in a paper supply receiving device 3. The paper supply 2 is formed as a paper roll 2. The paper roll 2 can have a net weight of 600 kg. The paper roll 2 can also be heavier or lighter. The paper roll 2 is arranged and fastened in the paper supply receiving device 3 without a pin or other tools; rather, it is clamped there pneumatically or hydraulically. A paper web 4 can be unrolled from the paper roll 2. The paper web 4 has a width of preferably more than 350 mm.

(6) The paper processing device 1 according to FIG. 1 further comprises a rolling arrangement 5, which is illustrated in more detail in FIG. 2. A paper web section 6 of the paper web is formed to a paper body with the rolling arrangement 5, wherein the paper body has substantially a cylindrical cross-section.

(7) Between the paper supply receiving device 3 and the rolling arrangement 5, a web tensioning control device is provided, by which the web tension is controlled. In addition, a lateral edge controlling device is provided, with which the paper web 4 is able to be conveyed in a controlled manner with regard to the position and direction of one or both lateral edges of the paper web 4.

(8) The paper processing device 1 according to FIG. 1 further comprises a high speed paper web conveying arrangement. Through the interaction of the stations, paper supply receiving device 3, web tensioning control device and lateral edge control, such a wide (more than 350 mm) paper web 4 is able to be successfully conveyed very quickly and precisely to the rolling arrangement 5. Thus, on the one hand, owing to the high conveying speed per unit of time, a large quantity of paper can be rolled, i.e., formed to a paper body. On the other hand, several paper sticks can be formed, by cutting to size, from the comparatively wide paper body per rolling- or forming process. As a result, the paper processing device 1 described herein operates quickly and, in so doing, produces more paper products than would be feasible according to the prior art.

(9) So that a paper web section 6 in the rolling arrangement 5 can be formed to a paper body, the paper web 4, originating from the paper supply 2, must be firstly cut to a desired length. This takes place in the high speed paper web conveying arrangement, where a perforation is formed in the paper web 4 by means of perforating blades, and where a paper web section 6 is separated from the paper web 4 by means of a crosscutting roller where the perforation was formed.

(10) So that in the rolling arrangement 5 a paper web section 6 can be formed to a paper body, the paper web 4 originating from the paper supply 2 must firstly be acted upon with a fold. This takes place in the paper web conveying- and folding device 19. The paper web conveying- and folding device 19 comprises five conveying rolls, wherein a conveying roll is formed as a profiled folding roll, which folds or creases the paper web section 6. The folding roll lies against a counter-roll, which is coated, and which has a conical cross-section with up to 2 mm conicity. The conicity is preferably less than approximately 1 mm and/or more than approximately 0.5 mm, for example approximately 0.7 mm.

(11) The rolling arrangement 5 according to FIG. 2 comprises a rolling drum 8, arranged rotatably on a carrier 7. A statically fastened cover 9, i.e., not movable during the rolling operation, is arranged above the rolling drum 8. A rolling space 10 is formed between cover 9 and rolling drum 8. The rolling space 10 has different dimensions over the circumference of the roller 8. The paper web section 6, which is cut to length and is provided with fold in the folding device 19, arrives into the rolling space 10 and is rolled up there to form a paper body which is very compact and almost cylindrical in cross-section.

(12) For fixing the edge of the paper web section 6 on the circumference of the shaped paper body, the paper which is to be processed is acted upon by an additive which is formed from water. This takes place in the additive adding device 11, which wets the lower region 12 of the rolling drum 8 with additive, i.e., substantially opposite the cover 9 on the underside of the rolling arrangement 5, by means of a rotor application system, so that in the further process the paper body is also acted upon with the additive. In this respect the paper is wetted indirectly, namely by the rolling drum being wetted.

(13) Following thereon, the paper body arrives into a cutting arrangement 13, where the paper body is cut to size so that one or more paper sticks are formed therefrom. Provision can be made that the paper body is firstly cut at the ends (end cut-off), and then the body (cut at the end side) is cut up into several parts (body cutting), wherein these cut parts form the paper sticks. The devices for the end cutting-off and for the body cutting can be separated spatially from one another in the cutting arrangement 13 or respectively in the paper processing device 1, and/or able to be controlled/regulated separately. Provision can also be made that the end cutting and the body cutting take place in a combined process step with accordingly configured cutting device 13.

(14) The end pieces are disposed of; for this a sorting- and/or screen device can be provided, which sorts out the short end pieces and further conveys the (longer) paper sticks. Preferably, the ends are separated by the cutting device 13, wherein they fall as paper residues or waste into the disposal device 14 which is arranged substantially under the rolling arrangement 5.

(15) A further station of the paper processing device 1 according to FIG. 1 forms the sorting device 15, which is formed in a multi-stage manner. The paper sticks are aligned there and deposited in at least one sorting box 16, wherein the paper sticks are arranged tightly in the sorting box 16 with as little intermediate space as possible, and parallel, i.e., without directional errors. This is essential for a quick and efficient further processing. The sorting device 15 comprises at least one vibration stimulation, by which a trough and/or the sorting box 16 is/are set into mechanical oscillation.

(16) A further station of the paper processing device 1 forms a drying device 17. It comprises a spiral conveyor, i.e., a conveying trough arranged in a helical manner, with a gradient. The spiral conveyor is able to be acted upon with warm or hot air by means of a blower device, so that the paper sticks which are conveyed in the spiral conveyor are dried, for instance for the residue-free removal of the (water) additive.

(17) A further station of the paper processing device concerns a post-treatment drum 18, in which the paper sticks can be fed to a post-treatment. A post-treatment can comprise a coating or a hardening or a quality control. The post-treatment drum 18 has a hexagonal cross-section and rotates with adaptable speed.

(18) The paper processing device 1 according to FIG. 1 is able to be set and adjusted with regard to several technical functions. This concerns the paper web speed, the cutting device(s), the rolling process, disposal measures, sorting- and conveying measures and the providing of the paper sticks for the further processing. Temperatures can be set/varied, for instance during drying or during post-treatment, the additive quantity and additive composition and the additive temperature can be set/varied, the vibration stimulation of the sorting device 15 is able to be changed with regard to frequency and amplitude, and many more. At least one control- and regulating circuit can be provided for the coordinated adjustment of these paper processing parameters of the paper processing device 1.

(19) FIG. 1 also represents one or more paper processing methods in which individual or multiple paper processing steps are carried out. A paper processing step concerns the providing of a paper web by means of a paper supply. A further processing step concerns the positionally- and directionally accurate conveying and/or cutting to length of the paper web. A further method step concerns the arranging of a fold or of a creased region on a paper web section. A further method step concerns the shaping of a paper web section with a rolling arrangement. A further method step concerns the adding of an additive, in particular with regard to a fixing of the paper web edge on the circumference of the (almost) cylindrical paper body. A further method step concerns the trimming of the shaped paper body, so that paper sticks with desired dimensions are formed. A further method step concerns the disposal of cutting residues or respectively paper waste. A further method step concerns the sorting and/or post-treatment of manufactured paper sticks.

(20) With the paper processing device 1 and/or with the paper processing method, accuracies or respectively tolerances are produced, which with respect to the nominal length of a paper stick are approximately 1/10 mm and with respect to the nominal diameter of the stick are approximately 1/100 mm. Within a manufacturing process, in which large quantities of paper sticks of particular nominal length and of particular nominal diameter are manufactured, the values named herein for deviations/tolerances are less due to the process stages and device components which are precisely coordinated to one another.
