There are many forms of rapier loom accessories. According to the configuration of the rapier, it is divided into three types: single rapier loom accessories, double rapier loom accessories and double rapier loom accessories.
1. Single rapier loom accessories
When a single rapier is used for weft insertion, a long rapier that is wider than the cloth width and its sword transmission mechanism are only installed on one side of the weaving tuck, so that the weft yarn is fed into the shed to the other side, or the empty rapier is inserted into the shuttle to reach it. After the other side holds the weft yarn, the weft yarn is pulled into the shed during the withdrawal process to complete the weft insertion. When the single rapier loom is pulling, the weft yarn does not go through the handover process in the center of the shed, so there will be no weft yarn handover error and weft yarn tension peak caused by the handover process. The rapier structure is simple, but the rapier size is large, and the stroke is also big. Most have been replaced by double rapiers due to their low machine speed and large footprint.
2. Double rapier loom accessories
When the double rapier is used for weft insertion, both sides of the loom are equipped with rapiers and corresponding rapier transmission mechanisms. In the process of starting to return, the weft yarn is transferred from the weft feeding sword to the weft receiving sword, and the weft yarn is pulled through the shed by the weft receiving sword. When the double rapier is used for weft insertion, the rapier is light and compact, which is convenient for reaching the width of the loom and running at high speed. In double rapier weaving, the weft in the center of the shed is reliable, and there is generally no error. Therefore, double rapier weft insertion is widely used in rapier looms.
