ROTARY KNIFE SYSTEM

摘要

A knife holder mounted upon the periphery of the knife roller in an apparatus for cutting lengths of webs such as paper is disclosed. The knife holder in the system disclosed is formed of an elastomeric material. The knife blades are held in place principally by friction in slots cut in the holder and seat themselves in the elastomer during set-up and cutting. Rapid and simple changes of knife blades without torquing or rolling in are achieved by fixing the elastomeric knife holder between readily located clamping members affixed to the surface of the knife roller, and alternative clamping members are provided for retrofit installations.
