Abstract
A reciprocating knife cutter for performing a cutting operation on sheet material is provided wherein the knife is not limited to reciprocation along a vertical axis. The cutter includes a guide which engages the knife, whereby the knife and guide are constrained to slide relative to one another along the longitudinal axis of the knife. The knife is reciprocated by an eccentric drive mechanism in a plane perpendicular to the drive axis of the mechanism, and the guide is pivotally mounted on the cutter so that the knife and guide remain in engagement as the knife is reciprocated. A sheet material cutting apparatus including such a reciprocating cutter is also provided. The invention also provides a knife sharpener for a cutting apparatus.
