<p>The mechanism is intended for grinding the teeth of a cutting chain (1), particularly of the type comprising cutting and support links, drive links and connector links. The chain is intermittently fed along a swivelable grinding head (40) and, when a cutting tooth comes into contact with a feeler (52), this closes a contact of a control which swivels the head into the appropriate working position. The support teeth are ground and radiused by a grinding shaft (18). The intermittent operation of the chain drive, grind head (40) and grind shaft (18) is infinitely variable to accommodate chains with different link pitch, cutting tooth and support tooth height.</p> |
