摘要： A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.

摘要翻译：公开了一种摩擦假捻线器。捻线机具有位于前辊的辊隙与导纱器之间的多个旋转摩擦片。摩擦板交错布置，用于摩擦加捻纱线。加捻纱线的纺丝方向与摩擦片的旋转方向相反。通过摩擦假捻机的作用，能够提高假捻装置与前辊间的纱线捻度，缩短扭转三角形高度，提高纺丝强度。由于纱线和摩擦片的外表面相对滑动和摩擦，摩擦阻尼力相应地减小了扭转三角形中的纺丝张力。

摘要： A filament positioning control device for composite spinning of filaments and staple fibers comprises a fixed shaft and a hollow shaft mounted thereon. Left and right spiral wheels with left and right spiral grooves are mounted on the hollow shaft. Left and right positioning plates are provided on outer sides of left and right spiral wheels, each having a guide pin engaged in a spiral groove. Each positioning plate has a guide block engaged in a guide rail. As the hollow shaft is rotated, the spiral wheels rotate accordingly and the guide pins on the left and right positioning wheels move along with the spiral grooves. Because spiral grooves on two spiral wheels have different directions, when the spiral wheels rotate, the distance between positioning grooves on the two positioning plates increases or decreases, thereby changing the distance between two filaments guided by grooves on the positioning plates.
摘要翻译：用于细丝和短纤维复合纺丝的长丝定位控制装置包括固定轴和安装在其上的中空轴。具有左右螺旋槽的左右螺旋轮安装在空心轴上。左和右定位板设置在左右螺旋轮的外侧，每个具有接合在螺旋槽中的引导销。每个定位板具有接合在导轨中的导向块。当空心轴旋转时，螺旋轮相应地旋转，左右定位轮上的引导销与螺旋槽一起移动。由于两个螺旋轮上的螺旋槽具有不同的方向，当螺旋轮旋转时，两个定位板上的定位槽之间的距离增加或减小，从而改变由定位板上的凹槽引导的两根细丝之间的距离。
