1. A system for measuring the length of a longitudinally moving strand, which comprises:

  • a roller mounted for revolution ahd having a peripheral surface in frictional engagement with the strand;

    a transducer coupled to said roller for generating a predetermined number of pulses for each revolution of said roller;

    means for multiplying said pulses by a factor proportional to the circumference of the peripheral surface of said roller;

    means for counting said multiplied pulses for a time period proportional to the magnitude of the circumference of said roller; and

    means for dividing said counted pulses by a factor proportional to the number of pulses generated by said transducer for each revolution of said roller to produce one pulse for each unit length of said strand engaging said roller.
