Sheet offsetting and registering apparatus

摘要

Sheet offsetting and registering apparatus including a sheet transport to transport a sheet to a receiving station; sheet restrainer to restrain the sheet during a portion of the transport path adjacent the receiving station, an offset registration member positioned along an edge of the sheet transport adjacent the portion of the transport path having the sheet restrainer and being movable laterally with a directional component perpendicular to the direction of sheet transport, and a pivotally mounted arm to laterally move the offset registration member perpendicular to the direction of sheet transport as said sheet is transported past the registration member to gently tap the edge of the sheet and offset and register it during its path of travel. In a specific embodiment the sheet restrainer is a rotatable inverting and stacking wheel with at least one arcuate sheet retaining slot into which a sheet may be inserted such that its beam strength is increased. The wheel is incrementally rotated from the load to an unload position to strip the sheet from within the slot registering the sheet at both its leading edge and one side edge.
