ABSTRACT:
Apparatus for automatically profile-forming saw teeth wherein the apparatus includes a carriage on which a saw blade to be toothed is securely fixed and an intermittent longitudinal drive is adjustable to set a distance between one saw tooth and an adjacent saw tooth of a template or saw blade used as a pattern which is attached to the carriage. An input shaft of a clutch/brake mechanism is provided to operate a longitudinal feed mechanism by pendular motion whereby longitudinal advancement of the carriage is achieved. Upon determining the desired longitudinal feed, the carriage is stopped and fed transversely toward a cutter by means of a transverse feed cam to cut new saw teeth or to recut teeth on an existing saw blade.
