Abstract

Hide is pressed against a cutter roll by a parallel backing roll against which the hide is clamped by a pressure roller. When the machine is not processing a hide, a grinding wheel can be traversed along the cutter roll to sharpen its blades. The cutter roll is now mounted in a housing which can be displaced between two positive locations. One of the locations closes the cutter roll against a hide. The other location opens the rolls and simultaneously brings the cutter roll into position for sharpening by the grinding wheel. Movement of the cutter roll housing is effected by a motor driven hydraulic system, pref. via a 180 degrees displacement of an eccentric giving linear movement to a connecting rod. Cutting away thickness variations in hides and skins to produce a sheet of uniform thickness. The cutter roll mounting is movable between only two positive locations. This is simpler and cheaper than moving the grinding head to a displaced cutter roll.
