  • Patent number: 4572497
    Abstract: In an apparatus for collecting sheets in a set thereof, two juxtaposed receiving stations (16,17) receive incoming sheets. A transverse conveyor means (53) is utilized to transfer the contents of one receiving station to the other receiving station. The transverse conveyor means (53) has a conveyor belt (58) adapted to be revolved through a course of travel. The upper portion of the course of travel of the belt (58) lies substantially in the plane of a sheet-supporting surface (18). The conveyor belt (58) has perforations (52) provided therein. A source of vacuum communicates through a suction block (57) to the perforations (52). According to a disclosed method, a sheet is transversely transferred from one receiving station to the other when conveyor belt (58) is revolved and the perforations (52) in the conveyor belt (58) communicate with the source of vacuum.
