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.
