Abstract

The present invention relates to a method for clamping the abb which is leaded to the inner side of the air-jet loom with reed (8). In the method, the abb which is leaded to the inner side of the air-jet loom deviates from the filling insertion direction (9) and is blown into the receiving opening (5a) in the catching channel (5), and is clamped therein. The positions of the nozzle (3) and the catching channel (5) are matching with the expected fabric width in the width range of the reed. In the assigned method the nozzle (3) and the catching channel (5) are configured at the beating-up side of the reed (8).

Description

technical field

[0001] The invention relates to a method of clamping an introduced weft thread according to the preamble of claim 1 , and to a corresponding stretching device according to the preamble of claim 6 , and to a loom implementing the method or provided with a stretching device. Background technique

[0002] In an air-jet loom, the weft thread drawn from the yarn storage device is accelerated through the main nozzle and the tandem nozzle and inserted into the shed, where the weft thread is further conveyed by means of so-called auxiliary nozzles or relay nozzles. During weft insertion, the weft thread is guided in a weft thread channel formed in the reed. Behind the reed is usually provided a stretching device for stretching the end portion of the weft thread on the receiving side and clamping it tightly. In the stretching device (the stretching device is often referred to as catcher or clamping device), the end part of the weft thread on the receiving side engage...
