  • Patent number: 4844439
    Abstract: A receiving device in a sheet conveyor for collecting occasionally one or more sheets (20) to be conveyed thereafter further by a conveyor (11, 12, 13) for continued sheet handling disposed beneath the device comprises a first and a second guide wall (7) located above the conveyer (11-13) in a spaced relationship, said guide walls extending transversely of the conveying direction of the conveyer and at a mutual distance somewhat greater than the length in the conveying direction of the sheets to be received and collected. Movable sheet carrying rods (9) are arranged between the guide walls (7) and in the lower edge area of the respective guide wall. Besides, sheet depressing fingers (10) are arranged to engage the uppermost sheet of the sheets (20) located in the device and depress the pile of sheets downwards towards the conveyer after the sheet carrying rods (9) have been moved out of engagement beneath said sheets (20).

  • Patent number: 4832327
    Abstract: Sheet conveyer intended to take charge of and convey part sheets (2', 2", 2"') obtained from a main sheet by dividing this into a predetermined number of parts and delivering it out of a cutter simultaneously and side by side. The conveyer includes a number of downward gradient planes corresponding to the number of part sheets. Each plane has a length as viewed in the conveying direction corresponding to the length of a respective part sheet. Adjacent planes are connected with one another by an intermediate portion substantially shorter than the respective plane. The connection of the intermediate portion to the preceding plane is rounded off. Furthermore, carrier elements are arranged so that when the planes have received a respective part sheet, the carrier elements push the last part sheet as viewed in the conveying direction from its plane to a position on top of the next part sheet. Thereafter the two part sheets lying on one another are pushed to a position on top of the following part sheet, etc.
