  • Patent number: 5692877
    Abstract: The present invention is for a method of stacking of thin sheets and a device for stacking of thin sheets according to the method. The sheets can be made from paper, plastic film or the like. The invention is primarily intended to be used in connection with print outs in computer centers delivering a continuous, rapid and lengthy flow of paper sheets. The paper is brought into the stacker on a conveyer (4) comprising a number of parallel bands arranged side by side, which are controlled by pulley wheels and supporting wheels (5, 6, 7, 8). The papers are delivered from the conveyer (4) in the slit between the paper stack (16) and a second conveyer (9) which also comprises a number of parallel bands arranged sidewise passing over pulley wheels (10 and 24). The paper stack is supported by several supports (14) each having a resilient supporting edge (17) towards the paper stack.
