Abstract
Provided is an improvement to the slide fastener constructing machine. The improvement provides a tooth-notching unit for forming a notch on each tooth on the stringer produced by a stringer producing unit which is a conventional unit and subsequently collected by a stringer collecting unit which is also a conventional unit. The tooth-notching unit includes a base having a passage allowing the stringer of teeth to pass therethrough and a grinding wheel or a circular disk cutter as cutting means provided on top of the passage for cutting a notch on top of each tooth on the stringer. To clear away rubbish produced by the notching process, various devices are provided including brushes and vacuum cleaners. The tooth-notching unit allows the slide fastener constructing machine to produce stringers of teeth that can be stitched securely to clothing. Its construction also allows easy maintenance.
