摘要: A yarn winding apparatus comprises two clutches (20,21), the input sides of which are continuously driven in opposed directions by a motor (18) or by respective motors (18,19). At any given moment one of the clutches (20) is engaged whilst the other (21) is disengaged, so that yarn traversing apparatus (13,14) is driven in a first direction to move the yarn (12) in one direction along a traverse path to a predetermined end of stroke location, whereupon a control device (22) causes disengagement of the one clutch (20) and engagement of the other clutch (21) to drive the yarn traversing apparatus (13,14) in the opposite direction and hence the yarn (12) in the reverse direction along the traverse path.
Preferably the clutches (20,21) are electrorheological fluid or magneto-rheological suspension clutches, each of which is coupled to a respective one of two spaced pulleys (15,16) around which travels an endless band (14), having a traversing yarn guide (13) thereon. The control device (22) may be programmable to vary the traverse speed and end of stroke locations to avoid patterning and ridged or collapsed package ends.摘要翻译: 纱线卷绕装置包括两个离合器(20,21),其输入侧由马达(18)或相应的马达(18,19)沿相反的方向连续驱动。 在任何给定时刻,离合器(20)中的一个被接合,而另一个(21)被脱开,使得纱线横动装置(13,14)沿第一方向被驱动以使纱线(12)沿着一个方向 (22)使所述一个离合器(20)脱开并与另一个离合器(21)接合以沿相反方向驱动所述纱线横动装置(13,14) 并因此沿着横动路径在相反方向上控制纱线(12)。 优选地,离合器(20,21)是电流变流体或磁流变悬架离合器,每个离合器耦合到两个间隔开的滑轮(15,16)中相应的一个滑轮(15,16),环形带(14)围绕该滑轮行进, 在其上引导(13)。 控制装置(22)可以是可编程的,以改变横动速度和行程位置的终点,以避免图案化和隆起或折叠的包装物端部。
