Fig. 3168.
First there is the pair of feed rolls the bottom roll of which is set sufficiently above the surface of the table to relieve the work of friction upon the table.
The work next meets an upper feed roll that acts to force the work down to the table surface (there being in this case no lower feed roll).
After passing the knives, the work is carried out by a delivery roll that also acts to keep the work down to the table face.
All three upper rolls are provided with rubber springs in the casings h, h′.
p, p, are the pulleys for the cutter head and b, those for the feed works, which have two speeds. The feed is thrown in and out by the lever d, which moves the pinion d endways and engages or disengages it from its gear wheel.
