Embodiment Construction

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

[0048] The pneumatic suction nozzle 6 attached close to the reed 1, the yarn clamp 7 for the weft thread, and the gu...

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 present invention relates to a device for catching and stretching weft yarn, a loom provided with such a device, and a method for catching and stretching weft yarn. Background technique [0002] It is known to use a variety of devices to catch and stretch the weft thread inserted into the shed of the loom 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 tied in the warp thread. [0003] EP 1722019 A1 describes a stretching device for weft yarns in air jet looms, which includes a stretching blower attached to the back of the reed, and it includes a catch for weft yarns attached to the front of the reed Groove. The end of the inserted weft thread is deflected towards the catch groove by the air flow from the stretching blower transverse to the insertion direction. [0004] In order to avoid that the end of the weft thread inserted through the shed an...
