APPARATUS FOR CUTTING SHEET MATERIAL

摘要

A sheet material cutting apparatus has a vacuum table with openings in its surface and a cutter wheel which moves in engagement with the table surface to cut sheet material spread on the surface. A valve is movable within each opening between an open and closed position. Each valve moves to its closed position within its associated opening in response to movement of the cutter wheel to a predetermined position relative to the associated opening. Each valve in its closed position defines a portion of the table surface.
