Embodiment Construction

[0047] figure 1 and 2 Shown is a part of an air jet loom comprising a reed 1 and a device 2 according to the invention. The reed 1 is assembled from a plurality of lamellae 3 with a U-shaped profile, which are attached next to each other and together form a U-shaped guide groove 4 for weft threads. During weaving, the weft thread is brought into the shed by means of an air flow into the U-shaped guide groove 4 which conveys the weft thread through the U-shaped guide groove 4 in the reed 1 . This air flow is generated by a main blower (not shown) and by a number of auxiliary blowers (not shown) positioned along the guide groove 4 . The reed 1 is fastened in a known manner to a schematically shown weaving sley 5 . In this case, the reed 1 is embodied continuously and extends past the device 2 according to the invention.

[0048] The pneumatic suction nozzle 6 attached close to the reed 1, the thread clamp 7 for the weft thread and the guide element 8 attached in the guide gr...

Abstract

Device and method for catching and stretching a weft thread (75) inserted through a guide channel (4) into a shed (69) of a weaving machine with a pneumatic suction nozzle (6), a thread clamp (7) and a guide element (8) for guiding the weft thread (75), wherein the guide element (8) is attached in order to deflect the weft thread (75) over a limited angle (A) with respect to the direction of insertion (B) and wherein the suction nozzle (6) is attached in order to catch the weft thread (75) at this angle (A). Weaving machine comprising a device of this type.

Description

technical field [0001] The invention relates to a device for catching and stretching weft threads, a loom provided with such a device and a method for catching and stretching weft threads. Background technique [0002] Various devices are known for catching and stretching the weft thread which is inserted into the shed of the weaving machine through the guide groove. In this case, the end of the inserted weft thread is held after reaching the other side of the shed and before this weft thread is bound in the warp thread. [0003] EP 1722019 A1 describes a stretching device for weft yarns in an air-jet loom comprising a stretching blower attached to the back of the reed and which includes a catch for the weft yarn attached to the front of the reed groove. The ends of the inserted weft threads are deflected transversely to the direction of insertion towards the catch grooves by the air flow from the stretching blower. [0004] In order to avoid that the ends of weft threads...
