Patent ID: RE38867

Claim:
A device for turning a conveyed sheet and simultaneously changing its conveying direction comprising: vertically spaced- apart upper and lower guide walls defining a longitudinally extending horizontal inlet slot lying in a first sheet plane, said inlet slot having a proximal end and a distal end and including first and second curved portions, respectively, at the distal end so as to define a diagonal bending slot having an axis of curvature in a plane substantially parallel to said first sheet plane; an inlet slot defined by first and second side walls and lying in a first sheet plane; inlet driving means for driving a leading edge of said sheet into said inlet slot; first and second curved walls defining a bending slot located diagonally to said inlet slot and having axes of curvature in a plane substantially parallel to said first sheet plane; an outlet slot defined by third and fourth walls and located adjacent said bending slot and wherein said third wall includes a plurality of openings; outlet drive means for seizing said sheet from said bending slot and driving said sheet through said outlet slot in a second sheet plane; and, a plurality of spherical roll elements located above said third wall but having portions thereof extending through said openings to contact said sheet as said sheet passes thereunder.
