Development Trend of the Rapier Loom
Over the past few years of development, the rapier loom has grown into one of the most commonly used types of weaving machines. Thanks to the application of advanced technology as well as weaving process innovation, the loom will continue to evolve as it improves its weaving performance.
Improved Loom Speed
- Increasing weaving speed has always been one of the goals that loom designers pursue. Based on the CAD andCAMtechniques, we have worked out the optimized designs for each part of the loom (especially the weft beating-up mechanism and weft insertion system) as well as the integrated loom as a whole. As its weft insertion rate is further improved, the rapier loom can be on a par with the air jet loom.
- The rapier head, rapier tape(belt), and rapier wheel are three key parts that determine the weft insertion rate. To fulfill the requirements for high weft insertion rate and low energy consumption, we have dedicated ourselves to improving the rapier structure and looking for new raw material to make the rapier. Our dedication has resulted in a more lightweight, reasonably structured rapier with smaller rapier head. Some designers even use the plasma covered alloy which is lightweight, smooth, and wear resistant to construct the rapier that is suitable for weaving wider ranges of weft yarns. The making material for rapier belt has also changed, from the past-time nylon, and carbon fiber or Kevlar fiber in 1980s, to the present-day high-strength fiber. Modern-day rapier tape does not buckle easily while creating little friction thereby extending the use life of the rapier belt.
- The state-of-the-art rapier adopts the "block design" to improve the loom's versatility and flexibility. The loom can be converted to correspond to a new product made of different fibers and with diverse weaving patterns
- The guide hook of the rapier was originally used to facilitate carrying the weft. During the weft insertion process, the friction between the rapier hook and rapier belt causes severe wear to the rapier belt thus shortening the use life thereof. The wear also increases the warp breakage. So removing the guide hook from the rapier has multiple benefits.
- The warp let-off, cloth take-up, dobby shedding, and weft selecting motions are all electronically controlled, with an aim to improve the automation and overall performance of the loom.
- To meet the increasing market demand for large width weaving machine, we have enlarged the reed with extra width.
- The rapier loom can be specifically designed to weave special fibers like glass fibers.
