ABSTRACT:
A variable rotary cutter assembly for transverse cutting of web material as it passes through a nip between rotating anvil and knife cylinders includes one or more cutter assemblies selectively positionable on the periphery of the knife cylinder. Each cutter assembly includes a base block adapted to be releasibly mounted on the knife cylinder, and a pair of pivotally connected block members one of which is adapted for releasibly mounting on an associated base block and the other of which carries an elongated knife blade and is outwardly pivotable about a pivot axis parallel to and spaced from the knife blade. Spring means bias the knife carrier block member outwardly about its pivot axis so as to effect a predetermined cutting pressure per unit length of the knife blade against the anvil while enabling self-adjusting movement of the knife blade to accommodate substantial variance in anvil and knife cylinder spacing and knife blade wear. The cutters assemblies may be mounted to effect single or double transverse web cuts, and stripper means are provided to strip trim strips cut from the web by pairs of knife blades.
