ABSTRACT:
Feeding apparatus for feeding material for a predetermined distance past a predetermined point on a feed-path comprises a pair of feed rollers, one of which is coupled to a stepping motor. A sensing means in the form of a light beam is provided on the feeding path at the predetermined point and when the material being fed intersects and interrupts this light beam, a control means for the stepping motor commences to count pulses transmitted to the motor. After a number of pulses have been counted which causes the motor to feed the material precisely to the predetermined location, the motor is stopped. The control means also has means for actuating a further apparatus (such as a crimping press) which performs an operation on the material. This control means is effective to delay energization of the crimping press is the press is not in a state of readiness for performing the crimping operation.
