摘要

An apparatus and associate method for cutting sheet material L spread in one or more layers over a supporting surface uses a reciprocating cutting blade 20 movable in two coordinate directions in the plane of the supporting surface defined by a penetrable bed 24 to enable the cutting blade to follow a desired line of cut relative to the sheet material. The cutting blade has a leading cutting edge that performs the actual cutting operation with a slicing and chopping action. During the cutting operation, the blade 20 shifts forwardly and rearwardly relative to the axis of reciprocation in synchronism with the reciprocation strokes of the blade 20.
