剑扦织机入纬率与纬纱滑脱问题的探讨

The Relationship Between weftlnserting Rate anb weft Slippage in Rapier Loom

本文采用应力波理论,结合实验对高速引纬时剑扦织机入纬率与 Gabler剑头的纬纱滑脱问题进行了分析,进而提出:一)高速引纬时,从纬纱滑脱的角度看存在一个允许的最高入纬率,当实际入纬率大于此值时,将产生纬纱滑脱。二)在剑头钳口中纬纱受的正压力和纬纱直径不同时,其允许的最高入纬率值是不同的。

Using strain wave theory and test,the article analysed the in- serting rate and weft slippage from a Gabler rapier clip.It is con- cluded that: 1.As the weft slippage is concerned,fhere is a maximum weft i- nserting rate,beyond the rate,Slippage mag accar. 2.The pressure force in the clip,the weft diameter,will affect the maximum value of the weft inserting rate.
