摘　　要：为了解决集聚纺设备改造后,主牵伸区上销不便于加装压力棒隔距块导致牵伸控制力减弱的问题,在后区附加双压力棒上销,增加后牵伸区的摩擦力界,减少后区意外牵伸,且能够使喂入主牵伸区的须条结构及抱合力好,从一定程度上缓解了牵伸过程中控制力不足的问题,有利于集聚纺纱线条干均匀度的提高。指出:要合理配置工艺,管好、用好后区双压力棒上销,避免反包围弧的出现;同时要注意胶辊、胶圈、罗拉精度的配合使用;该上销用在集聚纺细号纱线和普梳纱生产中,应用前景良好。In order to solve the problem with the top cradle in the main draft area which is difficult to install the pressure gauge, leading poor draft control after modification of the compact e- quipment, an additional installation is done of top cradle with double pressure bar is done in the rear area, increasing the friction section in the rear draft area, avoiding the accidental draft, making the sliver fed in the main draft area in good structure and good cohesive force, conse- quently solve the problem in certain extent of inadequate control of draft, favoring the mass eveness. It is pointed out that it is necessary to do proper configuration of process, good man- agement and use of the top cradle with double pressure bar in the rear area, avoiding the back- word grip hold arc while special attention be paid to the use of cots and aprons and the roller precision. It is promising to promote application of the product in spinning yarn of fine count and spinning of yarn conventionally combed.
