  • Patent number: 5139253
    Abstract: A conveying cable for conveying sheets includes a suction chamber with a supporting surface defining a shallow groove having a plurality of suction openings therein over which a perforated suction belt moves. A plurality of vent openings separately communicating with atmosphere are disposed adjacent the belt edges to prevent the sheets from being sucked against the table surface. The perforations in the suction belt preferably take the form of staggered slots which leave imperforate zones free along the center and adjacent the edges of the belt to help reduce undesirable belt stretching and the suction openings in the supporting surface increase in size adjacent the delivery end of the table.
