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°to 60°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.

A device for producing a bundle from an overlapping sheet by sheet stream of paper sheets according to a method wherein the sheets are serially free fall delivered to a downwardly moving inclined base while the sheets are continuously jogged and pressed as the stack is being formed, the serial free fall delivery of the sheets being interrupted after a predetermined number of delivered sheets and the compressing being effected by moving a compressor downwardly against the top of the stack at a rate faster than the stack is moving and the compressed stack is banded to form the bundle, said device comprising: a machine frame, a stacking table within said frame, said stacking table having means defining an inclined back wall for supporting the stack and base plate means arranged vertically relative to the plane of said defined back wall for receiving the free-fall delivered sheets, feed means carried by said machine frame for free-fall delivering a sheet by sheet stream to said stacking table, circulating conveying means carried by said machine frame, said base plate means carried on said circulating conveying means, means for pressing the formed stack also carried by said circulating conveying means, and means for separating the formed stacks one from the next following stack, said inclined back wall including stop face means for receiving the sheets in abutting relationship therewith at the terminus of their free fall; said circulating conveyor means comprising first and second circulating conveyors, said first circulating conveyor carrying said base plate means, and said pressing means comprising follow-up transporter plate means carried by said second circulating conveyor along a common path as the base plate means and substantially parallel thereto and drive means for moving said second circulating conveyor faster than said first circulating conveyor to bring the follow-up transporter plate means against the top of the stack carried by the base plate means during the movement of the base plate means.
