Embodiment Construction

[0026] exist figure 1 In the loom shown, two pieces of fabric 2, 3 are woven next to each other. The figure shows four pneumatic tuck-in devices 4 to 7 according to the invention, more specifically one tuck-in device 4 is arranged near the insertion side 16 of the shed 1 and one tuck-in device 5 is arranged at the shed 1 Near the opposite side 17 of , the two tuck-in devices 6 and 7 are arranged between the fabrics 2, 3 adjacent to each other. A cutting device 8 is added to the tuck-in device 4 , a cutting device 9 is added to the tuck-in device 5 and a common cutting device 10 is added to the tuck-in devices 6 and 7 . The weaving machine also comprises a sley 11 comprising a sley profile 12 to which a reed 13 is attached. In this case, the tuck-in devices 4 to 7 are attached to the sley profile 12 . In this case, the cutting devices 8 to 10 are also attached to the sley profile 12 . In order to allow the insertion of weft threads, the shed 1 is formed in a known manner us...

Abstract

The invention relates to a method for tucking an end (23) of a weft thread (19) into a selvedge (27) of a fabric (3) by means of a pneumatic tuck-in device (5) which blows an end (23) of an inserted and beaten up weft thread (19) extending past a selvedge (27) of the fabric (3) into a subsequent shed (1), whereby the tuck-in device (5) is moved back and forth along the selvedge (27) of the fabric(3) in synchronization with the reed (13) and blows in of this end (23) of the beaten-up weft thread (19) into a shed (1) while the tuck-in device (5) moves back and forth along the selvedge of the fabric.

Description

technical field [0001] The invention relates to a method for tucking the ends of inserted weft threads into the selvedge of a fabric by means of a pneumatic tuck-in device which blows the ends of the weft threads which beat up at the edge of the fabric. ) and extend beyond the fabric selvedge into a subsequent shed, and the invention also relates to pneumatic tuck-in devices. Background technique [0002] Pneumatic tuck-in devices are known, for example, from US 4957144 and WO 01 / 86047 A1. In order to be able to blow the ends of the weft threads into the subsequent shed, the pneumatic tuck-in device is located at least partially on the side of the reed, in front of the beat-up thread or in front of the fabric edge. In order not to impede the beat-up movement of the reed, it is known to omit the reed in the region of the pneumatic tuck-in, allowing the reed to move along the tuck-in all the way to the beat-up line. In order not to interrupt the reed in the region of the tuc...
