Problems solved by technology

[0004] If it is desired to use a drive wheel with a substantially vertical or inclined axis of rotation, the hooks are mounted on the rapier of known rapiers in such a way that the hooks cannot be properly oriented to catch the weft yarn before it is introduced into the shed or to make the hook effective adjusted to the position for exchanging the weft between two rapiers

Embodiment Construction

[0039] The loom M shown in Figures 1 and 2 is used to form two layers (fabric) N 1 and N 2 , such as weaving at the same time and mounted on the carriage 2 and located at two beating points P 1 ,P 2 Two layers of carpet T separated from each other by the downstream pile cutter 1 1 and T 2 , where the two corresponding sheds F defined by warp 4 and warp 4′ of the loom 1 , F 2 to two beat-up points P 1 ,P 2 Convergence, vertical displacement of warp yarn 4 is controlled by heddle 3 actuated by Jacquard harness, vertical displacement of warp yarn 4' is controlled by heddle 3' mounted on a heddle frame, and heddle The wires 3 and 3' are themselves driven by a multi-arm or cam mechanism (not shown).

[0040] For weaving fabric layers in cooperation with corresponding warp yarns N 1 and N 2 of weft yarn 5 1 and 5 2 Insertion into shed F through two rapiers 11 and 12 1 and F 2 , each rapier has its own hookable weft 5 1 or 5 2 rapier points or hooks 111, 121 and respe...

Abstract

The present invention relates to a rapier, method for manufacturing same, device for inserting weft yarns comprising such a rapier and loom equipped with such a device. The rapier comprises a flexible part and a hook which is fixed on the end of the flexible part and used to hold abb. The terminal of the flexible is arranged with a vertical groove, in which fixing a strengthened component, the strengthened component comprises at least a slot which is used to install the hook. The rapier is arranged with a tightening device which is used to hold immovably the connecting pieces or each connecting piece in the corresponding slot. In order to manufacturing the rapier, to hold the tightening device in the vertical groove immovably, then to insert the connecting pieces into the corresponding slots, and to keep the connecting pieces without movement through the clamping force applied by suitable apparatus.

Description

technical field [0001] The invention relates to a rapier for a loom and a weft insertion device for weft insertion. The invention also relates to a weaving machine equipped with such a rapier or equipped with such a weft insertion device, as well as a method of manufacturing such a rapier. Background technique [0002] In the field of weaving machines, it is known, for example, from DE-A-4131745 to use rapiers, each having a rapier or hook for dragging the weft thread and a part provided with an opening for receiving (the teeth of) a sprocket . The hook is mounted to protrude from the portion having the drive opening. [0003] In present day flexible rapier, single ply looms, each rapier drive wheel / sprocket has an axis of rotation substantially parallel to the warp axis. The flexible part or ribbon of the rapier thus has drive openings provided in the per se substantially horizontal top and bottom surfaces of the ribbon. [0004] If it is desired to use a drive wheel wi...
