  • Apparatus for controlled braking of a driven textile material engaging roll
    Patent number: 5052088
    Abstract: 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.

  • Apparatus for controlled braking of a driven yarn engaging roll
    Patent number: 4916783
    Abstract: 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.
