In the production process, the consumption of rapier loom high-speed filling insertion, rapier head and sword belt accounts for more than half of the total consumables of rapier loom. Therefore, how to effectively avoid the wear of the rapier head and sword belt is very important to save the production cost. 1. The harm of wear and tear At 400 revolutions per minute and 20 hours per day, the rapier head moves 960, 000 times per day. The most vulnerable parts of the head to wear are the head, wings and bottom.

Speed: Jet fast, rapier slow. 3, cotton, wool, silk, linen can be woven; Air jet for high count and density, rapier for thick fabric. 4. Rapier loom has low requirements for yarn, hairiness, nep and sizing. But air jet loom requires smooth yarn surface, less hairiness and high strength. Water jet looms are mostly suitable for hydrophobic fabrics due to the use of water. Woven machine with high precision, suitable for ultra-wide products. 5, color choice: rapier loom up to 16 colors, shuttle loom up to 6 colors, water jet loom up to 4 colors, air jet loom up to 8 colors.

The filling cut time is too early, the filling into the filling clamp is not deep enough, and the filling feed clamp force is too small. The weft tension is unreasonable and the clamping force of the clamping device is too small. 18. What is the reason for the waste yarn to be woven into the fabric? Waste side heald frame leveling time too late. The weft separates from the splice too late, resulting in too long waste edges.When the clipper enters the shed again, the waste yarn is carried to the next weave. The number of ends through the waste side heald frame is not enough, and the waste side is not effectively captured. 19. What is the reason for the temple pattern on rapier looms?
