    • Hoists for hoisting loads by means of a cable are in existence for a long period. There are various types of hoists, which include winches and capstans. Generally, the principle of operation of a hoist is based on the cable being driven by adherence of the cable to the drum of the hoist. A hoist is described according to an embodiment of the present invention. The hoist comprises a drum, a plurality of guides, a guide support and a biasing device for displacing a portion of a cable away from the guide when the drum is rotationally displaced to thereby hoist a load.

    • In a device for guiding and braking a yarn, a yarn brake comprises braking elements that are pressed flexibly against each other and act on the yarn in a pinch zone. The yarn brake is arranged in the yarn running path between a yarn feeder and a yarn receiver. A pneumatic threader also is provided which includes at least one air and yarn guide element that is disposed in the yarn brake and surrounds the pinch zone without contact. The air and yarn guide element comprising a receiving end, a delivery end and a guide channel provided therebetween, which is open towards the braking elements and from which the yarn is introduced into the pinch zone. The yarn is conveyed into the guide channel by means of an air flow past the pinch zone to the yarn receiver and is introduced into the pinch zone under the action of a produced drawing force.

    • A ball tension device for producing generally uniform tension in a traveling textile yarn, particularly in combination with a yarn storage and supply apparatus of the rotating drum type. A base portion has a yarn passageway with an upwardly facing annular ball seat. A ball freely rotatably rests on the seat to apply a force to a yarn passing over the seat and through the passageway. A ball retaining portion extends over the ball at an upward spacing sufficient to allow upward movement of the ball but insufficient to allow removal of the ball. These base and ball retaining portions project transversely from a mounting portion to provide a substantial open space to permit entry of a downwardly inclined traveling yarn. The ball retaining portion is imperforate to provide a cover for the ball and seat to shield the ball and seat from accumulation of lint. Similarly, the substantial open space around the ball and seat tends to minimize lint accumulation. The ball retaining portion is formed with an undersurface facing the ball and has an upwardly extending recess to accommodate upward movement of the ball while the ball retaining member otherwise retains the ball against displacement from the device. This recess may be elongated to accommodate transverse movement of the ball during threading. For the same purpose, the mounting portion may be formed with a recess in the surface facing the ball to permit movement of the ball transversely to accommodate threading.
    • 一种用于在行进的纺织纱线中产生大致均匀张力的球形张力装置,特别是与旋转滚筒式纱线存储和供给装置组合。 基部具有带向上的环形球座的纱线通道。 球可自由旋转地支撑在座椅上,以对通过座椅并通过通道的纱线施加力。 球保持部分以足以允许球的向上运动的向上的间隔在球上延伸,但不足以允许移除球。 这些基座和球保持部分从安装部分横向突出以提供实质上的开放空间,以允许向下倾斜的行进纱线进入。 球保持部分是无孔的,以提供用于球和座的罩,以防止球和座脱离棉绒的积聚。 类似地,球和座周围的实质开放空间趋于使棉绒积聚最小化。 球保持部分形成有面向球的下表面,并且具有向上延伸的凹部以容纳球的向上运动,而球保持构件否则保持球抵抗来自装置的位移。 该凹槽可以被拉长以适应穿线期间球的横向移动。 为了相同的目的,安装部分可以在面向球的表面中形成有凹槽,以允许球横向移动以适应穿线。
