纬纱在织口处的运动

本文在假设纬纱的抗扭刚度为有限值的基础上,建立了平纹织物在织口处组织单元的数学模型。利用所建立的模型,分析了纬纱在织口处相对于经纱的可能运动形式;讨论了不同形式的纬纱运动对打纬阻力的影响;找到了传统理论与实际存在矛盾的可能解释。最后,举例阐述了纬纱在打纬过程中,在织口处往复运动的经过。

MOVEMENT OF PICK AT CLOTH-FELL

A plain weave weaving model at cloth-fell, where the torsional rigidity of pick is assumed to have a finite value, is developed. Based on the model, possible forms of pick movement relative to the warp and effects of each form on weaving resistance are discussed. A possible explanation to the discrepancy of tranditional theory and practice is therefore discovered. Finally, an example is given to illustrate pick movement at cloth-fell during multiple beat-up operations.
