ABSTRACT:
Apparatus for cutting sheet material such as cloth as the material lies on a supporting surface having opposite sides comprising an elongated track adapted to extend across the supporting surface between the sides, the track having an operative surface over which the sheet material lies during cutting thereof, and a cutter operatively associated with the track for movement in opposite directions along the track for cutting the material. The apparatus further includes supporting structures on opposite ends of the track and associated with the opposite sides of the surface, the supporting structures including mechanisms for raising and lowering the track relative to the supporting surface, a drive operatively coupled to the cutter and to the raising and lowering mechanisms for moving the cutter along the track for cutting the material and for raising and lowering the track and a control operatively connected to the drive for causing the drive to move the cutter along the track for cutting the material and thereafter causing the drive to raise and lower the track. The control also includes provision for limiting the maximum length of travel of the cutter along the track as well as controlling the speed of travel thereof, allowing sharpening of the cutter and controlling the height to which the track is raised.
