The supply support (12) is oriented towards the opening of the stacking shaft (10) at in inclination from above and the completed stacks (1) are pushed out in a direction opposite the supply direction. This makes it possible to resume the supply operation after an interruption necessary for the pushing-out, before the stack (1) is pushed out of the stacking shaft (10) completely. This results in very short cycle times. The stacking method is suitable in particular for stacking folded printed products being supplied in the supply stream parallel to their folded edges.

    Abstract: A stacking apparatus for successively supplying boards and forming stacks of these boards and ordering these stacks in chosen patterns having: a feed conveyor for successively supplying boards; a stacking station connecting onto the end of the feed conveyor and having a supporting base and a stop for bringing to a standstill the boards supplied by the feed conveyor such that a stack of boards may be brought to a standstill until the thus formed stack has reached a desired height, the stop is subsequently moved from the front surface of the stack to the rear surface of the stack and from this position displaces the stack by pushing over the supporting base to a position in which the rear surface of the stack lies beyond the initial position of the front surface or in which the stack lies with its front surface against the rear surface of a previously formed stack; and a discharge device is present for removing formed stacks from the supporting base.

  • Patent number: 5954473
    Abstract: A variable cut sheet stacker has an internal stacking volume that is readily adjusted (in length, width and height) for a large variety of form sizes and thicknesses. First and second side members are spaced from each other horizontally and the positions between them can be adjusted, typically uniformly moved with respect to a central support. An inlet and support is provided in an inlet for the stacker, having a ramp, and an outlet end guide is adjustable with respect to the inlet end support. A top conveyor conveys cut sheets past the inlet support toward the outlet end guide in a first direction, and a bottom support is vertically spaced in an adjustable manner from the top conveyor for supporting cut sheets. The open interior volume defined by these elements is substantially a rectangular prism. The top conveyor includes a frame that is pivotable about a horizontal axis perpendicular to the first direction to move between a conveyance position and an adjustment-facilitating position.

  • Patent number: 5544583
    Abstract: A delivery interrupt mechanism for a printing machine includes a support frame having a stationary guide defining a guide path. A flexible finger is slidably supported by the guide for movement along a curved portion of the guide path while substantially conforming in shape to the curved portion between a retracted position and an extended position in which the finger extends from the frame to support leading edges of printed sheets in a printing machine. The finger is connected to a rotatable input shaft mounted on the frame so that the finger is moved along the curved portion of the guide path between its retracted and extended positions when the input shaft is rotated.

  • Patent number: 5484255
    Abstract: A collating machine for stacking sheets of paper fed seriatim thereto from a singulating feeder comprises a deck including a stacking area and a plurality of upper, endless, elastic belts, each of the belts moving around a pair of upstream and downstream pulleys suspended above the deck. A plurality of ramp guide blocks are adjustably secured to the deck between the pairs of pulleys, wherein a lower reach of each of the belts is lower than the highest section of the ramp guide blocks. There is structure for stopping each of the sheets at a downstream end of the stacking area which is a section of the deck between the stopping structure and the ramp guide block. Feeding structure is situated upstream from the pulleys for feeding each of the sheets over the ramp guide blocks toward the stacking area until a trail edge of the sheet moves from control of the feeding structure, wherein the belts convey the sheet to the stopping structure.

  • Patent number: 5178379
    Abstract: An improvement in a collating machine for stacking sheets of paper fed seriatim from a singulating feeder in the same order as the sheets appear in the singulating feeder. The collating machine includes at least one upper belt and one lower belt for frictionally engaging and transporting the sheets, and ramp structure for lifting a succeeding sheet of paper over and onto a preceding, stopped sheet to form a collation. The improvement comprises a device for stopping each of the sheets, including at least one straight, vertical member against which the leading edge of each sheet abuts while the collation is being accumulated. The ramp structure and the stopping device are the upstream and downstream ends of a stacking section in the collating machine. There is a device, adjacent the stopping device, for transporting the collation from the stacking section.
