Abstract
In order to provide a weaving loom having incorporated knitting threads, it is provided that the corresponding device for incorporating knitting threads comprises a feeding device for each knitting thread and, also for each knitting thread, a dipping guide needle (4) which comprises a thread guiding eye and which can be dipped between warp threads (2, 3) into the shed all the way below the insertion path of the weft-insertion device (7). Each one of the dipping guide needles (4) is slidingly arranged transversely to the warp direction, thus being able to move across the width of the woven material. Furthermore, there is provided a combing shaft (10) that comprises a plurality of teeth with intermediate spaces arranged therebetween for guiding the knitting threads. The combing shaft (10) that is slidable transversely to the direction of the warp thread and is rotatable around an axis in the direction of the rail is arranged transversely to the direction of the warp thread behind the stop position of the reed. The teeth of the combing shaft comprise protrusions which are designed in such manner that the teeth can retain the knitting threads in at least one rotational position of the combing shaft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
(22) In FIGS. 1 to 9, the working principle of the device is described in an explanatory manner, wherein, in this example, only one dipping guide needle is activated, the needle eye thereof thus being provided with a thread.
(23) The weaving loom shown in FIGS. 1 to 9 is a needle weaving loom, but the type of weft insertion is not decisive. The needle weaving loom comprises warp threads, which can form a lower shed and a upper shed, a weft needle with a weft thread, a dipping guide needle with a knitting or cover thread, a knitting needle for setting the selvage and, particularly, a combing shaft with protrusions for retaining the knitting or cover thread, and a guide bar, the combing shaft being both laterally slidable but also rotatable about its axisin the exemplary embodiment by 70 to 100, preferably about 70 to 80. FIG. 1 shows the weaving loom substantially in a resting position. This is illustrated by the fact that no shed is formed. In FIG. 2, the combing shaft and the dipping guide needle are already displaced compared to FIG. 1. In FIG. 3, a lower shed and an upper shed are formed, and the dipping guide needle has been moved towards the combing shaft. In FIG. 4, the reed has moved away from the stop position, the dipping guide needle is ready for dipping in, and the combing shaft is rotated by about 80 about its axis. The weft needle has already approached the region between the upper shed and the lower shed. In FIG. 5, the reed is located further away from the stop position, and the dipping guide needle is already dipped in. In FIG. 6, the reed is even further away from the stop position, and the dipping guide needle is dipped in below the level of the weft needle. In FIG. 7, the weft thread has reached the knitting needle for setting the selvage. In FIG. 8, the reed again moves towards the stop position, the knitting needle for setting the selvage holds the weft thread while the weft needle again moves out of the shed and the dipping guide needle rises again. In the situation of FIG. 9, the weft-insertion, that is, one weaving cycle, has been completed. The reed further moves towards the stop position, the knitting needle for setting the selvage has set the weft thread, the weft needle has again moved out of the shed and the dipping guide needle is again above the shed. It should be noted that the representation according to FIGS. 1 to 9 is a simplified representation in whichfor better understandingonly one dipping guide needle is shown. The rotatable combing shaft is shown in two different rotational positions in FIGS. 10 and 11.
(24) A weaving loom in which four dipping guide needles are arranged one behind the other is shown in FIG. 12 and shall be described hereinbelow. In FIG. 12, this weaving loom is shown substantially in a resting state. In FIG. 13 the weaving loom is then ready to introduce the knitting or cover thread. The weft needle is still outside the shed already formed, and the reed 1 is in the starting position. For simplicity, only one of the dipping guide needles 4 is shown with a knitting or cover thread 6 threaded in. In actual operation, the other dipping guide needles 4 canbut need notbe also provided each with a knitting or cover thread. The combing shaft 10 is in a position in which it is ready to incorporate the knitting or cover thread 6 for entraining the same. In FIG. 13, the weaving loom according to FIG. 12 is shown at a point of time when the dipping guide needle has been dipped into the shed and introduces the knitting thread. The weft needle is guided through the shed. FIG. 15 shows from sideways the weaving loom with dipping guide needle 4 dipped in, while FIG. 16 shows the same in a state in which the reed 1 is stopped, the dipping guide needle 4 is again in the upper position and the combing shaft 10 is twisted in such manner that it retains the knitting or cover thread 6 by a transverse movement of the guide bar. In FIGS. 15 and 16, there is shown the embodiment of the guide bar disposed on a holder 14 and rotatable about the guide bar axis 15 by means of a guide bar 1.
(25) In FIG. 16, there is shown a weaving loom according to a further exemplary embodiment of the present invention in which two guide bars for weaving two ribbons arranged adjacent to each other are shown, wherein each of the guide bars comprises one triple guide needle that is assigned to a respective combing shaft so as to weave onto each of the ribbons three appliqus arranged at a fixed distance. FIG. 18 then shows a typical appliqu 17 that is produced with such a weaving loom.
(26) In FIG. 19, the function of the combing shaft 10 is shown. The combing shaft 10 is located on the side of the product closely behind the stop line of the reed and is capable to either hold the knitting thread 6 by means of protrusions 11 or to release the samejust by a rotation. The incorporated threads are retained in a rotational position of the comb as long as the weft-insertion organ has reliably moved through the knitting thread. Without the protrusions 11 the knitting thread would slip off from the teeth of the combing shaft if the protrusions 11 on the tooth tip were not to retain it. The knitting thread would then suddenly come to lie diagonally across the warp, and the knitting needle loop formed by the dipping guide needle would become so small that the weft-insertion organ could not be moved therethrough in a reliable manner. This arrangement ensures process reliability, and in particular protects the knitting thread whichfor example as an antenna threadshould not be subjected to substantial loads. In FIG. 20, this relationship is again shown from above.
