ABSTRACT:
Sheets coming from a rotary printing press are conveyed to a drum mounted for rotation adjacent the delivery end of the sheet conveyor band. The drum comprises a plurality of like axially spaced discs, each disc having a series of spirally extending, equidistant pockets distributed uniformly about the periphery thereof. Each pocket defines an inlet opening for receiving a sheet as the drum rotates successive inlet openings into sheet receiving relationship with the delivery end. Strippers are mounted peripherally spaced from the delivery end at a sheet stacking station between the discs of the drum to strip the sheets from the pockets and stack them.
