ABSTRACT:
In an automatic machine for cutting zippers from a common zipper tape, feed rollers are positioned to direct the common tape to the cutter. The sliders on the tape are detected by a photoelectric detector upstream of the feed rollers, in order to develop a signal of determined duration for enabling a bottom stop detector positioned upstream of the slide detector. A delay device is provided to actuate the cutter a determined time following detection of a bottom stop by the stop detector.
