摘要： Apparatus for controlling tension in a traveling yarn includes sequential yarn-engaging driven and idler rolls, the driven roll having a stationary rotational axis and the rotational axis of the idler roll being movable in a defined path responsive to tension variations in the traveling yarn, a piston-and-cylinder biasing assembly for urging the idler roll into yarn tensioning engagement, and a potentiometer for sensing tension-responsive movement of the idler roll and operatively associated with the driven roll for varying its yarn driving speed to compensate for such tension variations. In one embodiment, the idler roll follows a horizontal path of movement and is spaced considerably from the driven roll for functioning as a yarn accumulator. In a second embodiment, the idler roll pivots through an arcuate path of movement centered about the driven roll.
摘要翻译：用于控制行进纱中的张力的装置包括顺序的纱线接合驱动和惰轮，所述从动辊具有固定的旋转轴线，并且所述惰轮的旋转轴线可以响应于所述行进纱线中的张力变化而在限定的路径中移动，用于将惰辊推动到纱线张紧接合中的活塞和气缸偏置组件，以及用于感测惰辊的张力响应运动并与从动辊可操作地相关联的电位计，用于改变其纱线驱动速度以补偿这种张力变化。在一个实施例中，惰辊遵循水平的运动路径，并且与从动辊明显地间隔开，用作纱线储存器。在第二实施例中，空转辊通过以驱动辊为中心的弧形运动路径枢转。

摘要： Apparatus for controlling tension in a traveling yarn being delivered to a driven winding apparatus includes sequential yarn-engaging first and second idler rolls, one having a stationary rotational axis and the rotational axis of the other being movable in a defined path responsive to tension variations in the traveling yarn, a piston-and-cylinder biasing assembly for urging the movable roll into yarn tensioning engagement, and a potentiometer for sensing tension-responsive movement of the movable roll and operatively associated with the winding apparatus for varying its yarn winding speed to compensate for such tension variations. In one embodiment, the movable roll follows a horizontal path of movement and is spaced considerably from the stationary roll for functioning as a yarn accumulator. In a second embodiment, the movable roll pivots through an arcuate path of movement centered about the stationary roll.

摘要： A clamping brake for selectively braking each thread in a warp mill having a plural number of threads includes first and second brake disks which can move together to brake a thread in a thread guide positioned between the brake disks. The second brake disk is moved by pneumatic fluid, opposed by either gravity or a spring force.
