ABSTRACT The lengths of at least a pair of limp workpieces fed through a work station are controlled by pressing each of the workpieces into engagement with a separate toothed wheel and by controlling the rotational velocity of one of the toothed wheels as a function of the rotational valocity of the other toothed wheel. In one preferred embodiment the control of the rotational velocities of the two wheels is accomplished by means of a differential near and a motor which operates under the control of rates of feed sensors which monitor the rates of feed of the two workpieces.
