ABSTRACT:
Paper sheets are advanced seriatim between high speed upper and lower conveyor belts across a gap onto a slower speed multi-belt conveyor with which the upper high speed belts cooperate to form a sheet controlling tunnel. Static eliminating and sheet knock-down air is directed through the upper high speed belts and into the sheets traversing the gap. Advance of the sheets across the gap is facilitated by impermanent wave-like longitudinal stiffening rib deflection of the sheets where they leave the high speed conveyor belts. After each sheet has been fully received on the slow speed conveyor, its high speed travel is stopped by stop roll means to assure overlap of a succeeding sheet thereon. The stop roll means cooperate with the slower speed conveyor belts to effect impermanent wave-like longitudinal jam preventing stiffening rib deflection of the sheets.
