    • A double-twist apparatus has a support provided with a journal in which is rotatably received a sleeve having an eccentric bore in which is centered the shaft of a twist spindle. A whorl carried on the shaft is engageable with a flat belt and rotation of the eccentric spindle within the fixed journal can move the whorl into and out of engagement with the belt. A lever is provided on the sleeve for angular displacement of this sleeve and a spring normally urges the sleeve into a position corresponding to engagement of the whorl with the belt or disengagement of the two. In the case of the spring urging the sleeve into the engaged position a toggle linkage is provided to hold the device in this position. In the arrangement where it urges the whorl away from the belt a spring-loaded device operated by a thread-tension sensor downstream of the apparatus is provided to stop the device in case of thread rupture. A brake is provided on the spindle shaft to arrest it when it is swung out of engagement with the belt.
    • 双捻装置具有设置有轴颈的支撑件,其中可旋转地容纳有具有偏心孔的套筒,该偏心孔以扭转轴的轴为中心。 轴上携带的螺纹可与平带接合,并且固定轴颈内的偏心轴的旋转可将螺旋移动进入与皮带的接合。 套管上设有一个杠杆,用于该套筒的角位移,弹簧通常将套筒推动到对应于螺旋与皮带接合或两者分离的位置。 在弹簧推动套筒进入接合位置的情况下,提供肘节连杆以将装置保持在该位置。 在其推动螺旋离开皮带的布置中,提供由装置下游的线张力传感器操作的弹簧加载装置,以在线断裂的情况下停止装置。 当主轴摆动与皮带接合时,制动器被设置在主轴上以阻止它。

    • The package lift apparatus serves for lifting a wound yarn package in contact with a rotating drive roll which drives the yarn package in a textile machine. Known equipment of this type requires a considerable degree of manual operation or exhibits a relatively complicated, and thus, expensive construction which is prone to malfunction. These drawbacks are avoided with the inventive yarn package lift apparatus which contains a piston-and-cylinder unit, wherein the piston rod of the piston carries a package support member. During one time interval the piston is exposed to a drive force which moves the package support member against a lower region of the package surface and thus lifts the yarn package from the drive roll. When the package support member is in an extended position the pressure or force exerted by the yarn package upon this package support member causes canting of the piston against the cylinder, so that from the moment of such canting of the piston the package support member is fixedly clamped or jammed in its yarn package supporting position. Due to the action of a continually exerted return or restoring force the piston and the package support member move back into their starting positions whenever there is merely exerted a slight brief lifting of the yarn package.
    • 包装提升装置用于提升卷绕的纱线包装,其与在纺织机器中驱动纱线包装的旋转驱动辊接触。 这种类型的已知设备需要相当程度的手动操作或者表现出相对复杂的并因此昂贵的易于发生故障的构造。 本发明的纱线包装提升设备包含活塞和缸体单元,其中活塞的活塞杆承载包装支撑件,可避免这些缺陷。 在一段时间间隔期间,活塞暴露于驱动力,该驱动力使包装支撑构件抵靠包装表面的下部区域移动,从而将纱线卷装从驱动辊提升。 当包装支撑构件处于延伸位置时,由纱线卷装施加在该包装支撑构件上的压力或力使得活塞相对于气缸倾斜,使得从活塞的这种倾斜的角度来看,包装支撑构件是固定的 夹紧或卡在其纱线包装支撑位置。 由于连续施加的返回或恢复力的作用,只要仅仅施加了纱线包装的轻微的提升,活塞和包装支撑构件就移回到它们的起始位置。
