Apparatus for stacking sheets in corner registration

Claim 1

Apparatus for stacking sheets in corner registration, comprising: coacting opposed sheet feed means of tapered cross-section and spanning the total width of a paper path adapted to receive sheets fed from a feed source and forward the sheets through said paper path for further processing, said tapered feed means, due to said tapered cross-section, rotating the sheets in the planes thereof individually by approximately 45° as they are forwarded with the sheets being positively gripped throughout their rotational movement such that they pass through a nip formed between said coacting feed means in a straightforward rolling manner; and stacking means located downstream from said coacting sheet feed means and adapted to receive the sheets forwarded by said coacting feed means, said stacking means being downwardly inclined in relation to said coacting feed means and including a registration corner means diagonally opposite said feed means, said registration corner means being rotated 45° in relation to said coacting feed means such that a V-shaped intersection is presented thereby to incoming sheets to said stacking means whereby sheets forwarded toward said registration corner means by said coacting feed means are forwarded with a corner thereof in line with said registration corner means V-shaped intersection.
