摘　　要：对影响织机入纬率的诸多因素进行分析,表明对于使用梭子或载纬器的所有织机(如:传统有梭织机,片梭机和多相织机)来说,影响因素基本上是相同的。一台织机的相数由同时引入纬纱的梭子或载纬器平均数决定。它表明多相织机是以高的相位数来补偿其较低的梭子飞行速度。本文通过对多相织机与多梭口织机关系和影响入纬率与投梭时期参数的分析得知,提高梭子的飞行速度和适当增加“相数”都能获得高的入纬率。这里适当增加“相数”和多相织机的相数不同,它是通过将校口和打纬机构分开成几个部分取得的。这样做还可以避免在现有多相织机中产生的许多纺织与工程上的问题。An analysis of the weft-insertion rate of weaving machines shows that it is essentially the same on all looms in which shuttles or weft carriers are used, such as conventional shuttle looms,gripper-shuttle looms and multi-phase looms. The phase number of a loom is defined as the average number of shuttles of weft carriers inserting weft simultaneously. It is shown that existing multi-phase looms must have high phase numbers to compensate for their low shuttle velocity. The analysis of the relation between multi-phase and multi-section looms and the research in parameters determining the weft-insertion rate and the pick period suggest that looms with high-velocity flying shuttles would achieve equally high weft - insertion rates with moderate increases in the phase number. Such moderate increases in the phase number can be obtained by dividing the shedding and beat -up motions into a comparatively small number of sections. The suggested alternative can avoid many of the textile and engineemg problems arisng in existing multi-phase looms.
