  • Patent number: 4372201
    Abstract: A device for producing a bundle from an overlapping sheet-by-sheet stream of folded printed sheets on a slope where the stream is initially conveyed to an inclined moving stacking table having a base, in a free fall delivery, to form a stack on the base and inclined toward the vertical. The stacking table is carried on a circulating conveyor and is moved downward in an inclined condition to receive the sheets. The circulating conveyor is provided with a followup transporter following a common path with the base and moves faster than the base. The followup transporter thus engages the top of the stack to compress same during formation thereof. A tension band arrangement effects jogging of the sheets on an inclined slope of 10.degree. to 60.degree. in the conveying direction so that each sheet slides toward the inclined slope under its own weight and/or by the push of the following sheet.

  • Patent number: 4311090
    Abstract: Method for producing a bundle from an overlapping sheet-by-sheet stream of folded printed sheets on a slope where the stream is initially conveyed and is rerouted upward in order to form a stack inclined toward the vertical. The method comprises the steps of stacking the sheets on a moving base arranged at a right angle to the slope and moving downward on the slope; interrupting the flow of sheets after a certain number of sheets is stacked by cyclically forming a gap during conveyance to the slope, placing a firm support on the last sheet of the stack, compressing the stack and forming the stack into a bundle. The step of stacking includes jogging the sheets on a slope inclined toward the vertical by 10.degree. to 60.degree. in the conveying direction so that each sheet slides toward the slope under its own weight and/or by the push of the following sheet. The sheets drop onto the stack in a free fall.
