多梭口织机入纬率研究

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栽纬器的所有织机(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，它是通过将梭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。

Evenness Control of Rapier Loom Tension by Using Neural Network

The neural network model （NNM） is used to control the evenness of rapier loom tension and to model the uncertain parameters of drafting process. This model can estimate recursively the tension and incorporate predictive control strategies. After controlling the effect testing, it can be seen that the behavior is excellent following different set point and variations, such as the diameter of the beam of weaver, air stream, density of warp and weft, type of textile, etc. An optimum steady state scheme has been fixed in keeping evenness of tension of loom. This method improves obviously the efficiency and quality of production.     

THE POTENTIALITY OF ENERGY-SAVING IN SHUTTLE LOOMS

In this paper,the effects of loom speed fluctuation on the mean speed and on the power ofdriving motor were investigated and the expressions for these effects were derived.Based on theenergy relationships,a new index of equivalent fluctuation was introduced,the connection be-tween this equivalent fluctuation and the energy of speed function on frequency domain was thenfound.In addition to the above theme,the residual kinetic energy of the shuttle and pickingmechanism,taken as a considerable part in the potentiality of loom energy-saving was also ana-lysed.According to the results of theoretical analyses,the ways of energy-saving in looms weresuggested.Finally,taking the loom of 1511 type as a practical example,the potentiality ofenergy-saving was calculated.

An Analysis and Prevention of Stop Marks in Weaving

The cause of stop marks of fabrics in weaving is introduced, and the floating displacement of the cloth fell during loom stoppage is a primary cause of stop marks. The stop marks caused by fabric system are analyzed. A new method to eliminate stop marks by using the electronic let-off system is presented. This new method needn't any special detecting equipment, it can control the fell position by the powerful control program, so the cost is decreased greatly. The method is so flexible that can be applied to weaving all kinds of fabrics.
