摘要： In a textile warping system having one or more driven yarn engaging or yarn winding rolls, e.g. a driven warp beam, braking of each driven component is controlled by an individual pneumatic brake operated by a central programmable logic control system to brake the driven component according to a predetermined relationship of decreasing speed to elapsed braking time.

摘要： In a textile draw warping system having independently driven sets of draw rolls and an independently driven warp beam, synchronous braking of the driven components is controlled by individual pneumatic brakes at each driven component operated by a central programmable logic control system to brake the driven components at respective rates of deceleration preset to maintain constant speed ratios between the driven components during braking. Auxiliary control of dynamic braking and driving of the several drive motors corrects deviations in the driven components' predetermined rates of deceleration.

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： 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.
