Embodiment Construction

[0037] figure 1 A detail of a rapier loom is shown with a device 1 for weft thread 2 insertion according to the invention. For example, a rapier loom can comprise a reed 8 for striking the inserted weft thread and a handle 2a from which the weft thread 2 is removed as it is inserted. Moreover, the rapier loom can comprise shed forming equipment, which can be equipped with healds 7a, 7b for example, in order to raise some warp threads 12a, 12b, and lower some more warp threads at the same time, so that the raised and lowered warp threads Shedways 10 are formed between them. The device 1 generally comprises a rapier belt 3b movable in the insertion direction and a rapier head 3a for weft feeding rapiers for inserting the weft thread 2 into the shed 10, and a rapier belt 4b movable in the insertion direction And a rapier head 4a for a weft receiving rapier to receive and forward weft from a feed rapier located in the central area of ​​the shed. Possible aspects of the device 1...

Abstract

An apparatus (1) is presented for the insertion of a weft thread (2) into a shed (10) of a rapier weaving machine. The apparatus (1) includes a rapier tape (3b) movable in the insertion direction, a rapier head (3a) at the same and at least one guide part (5) which is provided at the rapier tape or at the rapier head as well as a plurality of guide elements (6.1-6.i+1) which cooperate with the guide part to guide the rapier tape or the rapier head in the shed, wherein the start of the guidance of the guide part by the guide elements is delayed until the rapier tip ( 3) is at a distance of at least 14 cm in the shed.

Description

【Technical field】 [0001] The present invention relates to a device and a method for inserting a weft thread into the shed of a rapier loom according to claim 1 and according to the respective preambles of claim 6, and to having such a device or being equipped to achieve this method of the rapier loom. 【Background technique】 [0002] In a rapier loom, the weft thread is usually inserted into the shed by means of a bringer rapier fixed to a rapier rod or a flexible tape (flexible tape), and passed through a joint at a transfer point located in the middle of the shed. Taker rapiers are accepted and forwarded. The task of the delivery rapier is to reliably tension the emerging weft thread, to insert this weft thread into the shed and to feed it precisely to the weft receiving rapier. The task of the weft-taking rapier is to reliably receive the weft thread, to transport it forward into the shed and to release the weft thread at the end of the weft insertion. Each rapier compr...
