ABSTRACT:
An apparatus, for automatically processing a slide fastener chain to which a succession of fly strips is attached, comprises an intermittently operative feed unit for feeding the fastener chain along a longitudinal path, a first cutting unit disposed upstream of the feed unit for forming element-free gaps in the fastener chain near or at ends of successive fly strips, and a second cutting unit disposed downstream of the feed unit for severing the fastener chain at such element-free portions. The apparatus also includes a measuring unit disposed upstream of the first cutting unit for measuring the amount of the fastener chain having been fed by the feed unit, and a detector disposed between the first cutting unit and the measuring unit for detecting ends of successive fly strips. The measuring unit and the detector are electrically connected to a processing circuit which produces output signals to control the intermittent operation of the feed unit in timed relation with the operations of the first and second cutting units.
