AUTOMATIC BLADE DIAMETER COMPENSATION FOR PAPER LOG CUTTERS

摘要

An apparatus for transversely cutting logs of web material which are sequentially advanced along a first path and a rotating disc blade is mounted in said apparatus for movement in a second path through said first path from one side of the other of the first path to transversely sever said logs, a sharpener is provided in said apparatus for sharpening said blade. The apparatus is provided with structure for incrementally changing the relationship of said sharpener and said blade to compensate for diameter reduction of said disc blade. The apparatus is equipped with structure for altering the relationship of said paths to also compensate for diameter reduction of said blade.
