Description

Technical Field

[0001] This utility model relates to the field of loom technology, and in particular to a rapier head for a rapier loom. Background Technology

[0002] A rapier loom is a shuttleless loom that uses rapiers to guide the weft. A double rapier loom has rapiers and corresponding rapier transfer mechanisms on both sides. These two rapiers are called the feed rapier and the receive rapier, respectively. During weft insertion, the feed rapier and the receive rapier move from the sides of the machine towards the center of the shed. The weft yarn is first grasped by the feed rapier and fed to the center of the shed. The two rapiers meet at the center of the shed, and the weft yarn is transferred from the feed rapier to the receive rapier. Then, the feed rapier and the receive rapier each retreat, and the receive rapier pulls the weft yarn across the shed.

[0003] There is a type of yarn made of wide, flat plastic or carbon fiber, approximately 10 mm wide and over 1 mm thick. In actual production, it is generally made manually. For this type of special yarn, there are no suitable cutting tools available on the market to match it, and fully mechanized production is currently impossible. This results in high labor intensity, low efficiency, and inconsistent quality, hindering product standardization and mass production. Utility Model Content
