| description | An apparatus for applying sheets to substrates including a rotating blade roller with a blade on its surface; a vacuum roller rotating with the blade roller, oriented parallel to the blade roller, and with a surface adjacent to the blade roller surface; at least one slot in the vacuum roller surface into which the blade is inserted as the rollers rotate; and a feeder for feeding a continuous sheet between the rollers so that the sheet is cut into segments. The vacuum roller surface includes surface holes connected to a vacuum source during cutting and disconnected after cutting and manifold holes parallel to the roller axis and located in a circle below the surface. The manifold holes have open ends located at one end of the vacuum roller and are connected to the surface holes. There is at least one plate adjacent the end of the vacuum roller with the open ends. The plate includes at least two curved grooves on the surface matching the shape of the path traveled by the open ends. One of the grooves is connected to the vacuum source, and the other is connected to a positive pressure source. The end plate includes a threading groove attached to a vacuum source and located adjacent to a portion of rotation of the vacuum roller which precedes the location at which the sheet first contacts the vacuum roller. The threaded groove matches the shape of the path traveled by the open ends. |
