ABSTRACT:
An apparatus for measuring the amount of yarn withdrawn from a warp beam mounted on the frame of the warp beam knitting machine is disclosed. A support arm is mounted on the frame and a lever arm is pivotally mounted on the support arm. A pressure roll is supported on the lever arm and engages the yarn wound on the warp beam. The pressure roll is operatively connected to a signal generator which generates pulses representative of the length of yarn withdrawn from the warp beam. A limit switch is mounted on the support arm and is adapted for electrical connection to the main drive mechanism of the warp knitting machine. The limit switch has open and closed positions adapted for controlling operation of the knitting machine. When the switch is closed the knitting machine is operable. The support arm is pivotally movable into 1) a biased, operative position pivoted toward the warp beam in which the pressure roll is engaged with the warp beam and the limit switch is closed; 2) an intermediate position in which the support arm is pivoted away from the warp beam, the limit switch is open, and the pressure roll engages the warp beam; and 3) an inoperative position in which the support and lever arms are pivoted rearwardly from the warp beam and the limit switch is open.
