DISPOSITIVO PER IL TAGLIO DI MATERIALE IN FOGLIO PARTICOLARMENTE PER IL TAGLIO DI TESSUTI

摘要

An apparatus for cutting sheet material spread in one or more layers over a supporting surface uses a reciprocating cutting blade cutter movable in two coordinate directions in the plane of the supporting surface 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 action. During the cutting operation, mechanical means within the apparatus produces blade dither about the axis of reciprocation in synchronism with the reciprocation strokes of the blade.
