The Stability of Weft Insertion of CRT – 83 Carpet Rapier Loom
Applied Mechanics and Materials, 2013CRT- 83 carpet rapier loom is a kind of high-grade rigid rapier loom，the weft yarn will give looms to demand higher stability of the weft insertion. Theoretical analysis based on the theory research of the stability of clamping weft and weft handover shows that the rapier deformation，slipping force and the depth of clamping are main factors influencing

Numerical simulation model for optimisation of weft insertion on projectile and rapier looms
Mechatronics, 1995Abstract A high weft insertion rate in a weaving loom can cause yam breakage and a non-uniform tension in the weft yarn at shed closure. A numerical simulation model is proposed that is able to calculate the tension profile in the weft yarn during insertion.

Deep learning-based digital twin for intelligent predictive maintenance of rapier loom
Journal of Intelligent and Fuzzy SystemsThe rapier loom works in a complex environment and operates at high speeds. It is inevitable that its performance will deteriorate during the production process, which in turn will cause faults. The development of maintenance has undergone the transition from “regular maintenance” and “post-event maintenance” to “predictive maintenance”.

Filling Velocity Changes at Tip Transfer on Rapier Looms: A Simple Analysis
Textile Research Journal, 1996In rapier filling insertion by tip-transfer between two half-width rapiers, the filling clamps may be operated either positively or negatively at transfer. The trajectories of the transfer point on the giver and the clamping point on the taker rapier are observed for both cases.
