Abstract:

With regard to the weft density distribution condition of four-gear continuous take-up mechanism on loom, this study has developed a “weft density demonstration and optimization system” based on VFP. Through inputting the parameters of the take-up mechanism into this system, analyzing the rule of density distribution, and finding out cause leading to uneven distribution of weft density, it concluded that by using 4 transform gears the continuous take-up mechanism can meet the requirements for weft density of fabrics, but it can not guarantee the continuous distribution in all density gradients. It is proposed that for cotton, wool and linen production, different configuration parameters of the gear should be considered. 3 sets of specific and optimized programs for gears more than 17 teeth are presented, in which, at least there is one group of spare gear that consists of 7 only.
