ABSTRACT:
A pair of colinearly movable, reciprocating paddles for bumping the side edges of sheets flowing serially along a feed path is disclosed. The sheets travel between the reciprocating paddles in a direction generally perpendicular to paddle movement. The paddles jog the sheets into a correct alignment position to establish registry between the sheets and, for example, the plate cylinder of an offset printing press supplied with the sheets. The distance between each paddle and the sheet feed path centerline can be adjusted during reciprocating movement of the paddle to meet registry requirements. A disengagement mechanism permits separate use of either paddle.
