Abstract
A feed device for machines which act on saw teeth, to sharpen the teeth, position the teeth, add hard metal plates to the teeth or the like, which accommodate wide pitch distances between saw teeth and variations in pitch distances between the teeth of the saw. The feed device includes a first reciprocal feed pawl which advances the saw a preset distance on each stroke and a second reciprocal feed pawl which additionally advances the saw to accommodate wide pitch distances between saw teeth and variations in saw tooth pitch patterns.
Claims12
A saw feeding device for a saw machining apparatus which comprises a first mechanism acting on a saw in the machine to advance the saw a preset distance, a second mechanism acting on the saw to advance the saw in the machine in the same direction as the first mechanism a preset distance beyond the distance advanced by the first mechanism, and control means selectively activating said mechanisms for accurately positioning the teeth of the saw for a machining operation by said machining apparatus.
A saw feeding device for a saw machining apparatus which comprises a reciprocable feeding pawl performing advance strokes from a starting position to an end position on a tooth of a saw for moving the tooth into a machining position in said apparatus and then returning to its starting position, and an additional pawl adapted to perform advance strokes from its own starting position into its own end position on a tooth of the saw in said apparatus, means operating said additional pawl to perform its advance strokes between the strokes of the feeding pawl whereby said additional pawl advances a saw tooth by an adjustable distance in said machine and then returns to its starting position, means controlling the end position of the additional pawl relative to the starting position of the feeding pawl so that the additional pawl advances the saw selectively a zero distance or a distance equal to the distance between a plurality of successive teeth of the saw so that the sum of each advance stroke of the feeding pawl and the additional pawl at least equals the greatest distance between adjacent teeth of the saw.
