ABSTRACT:
A positioning conveyor is incorporated in a conveyor system for adjusting the position of a sheet on the conveyor system. The positioning conveyor has two belt type conveyor sections that are independently movable transverse to the feed path and are utilized to adjust the position of the sheet. The sheet is scanned by a scanner and the data is input to a computer. A vacuum zone on each section provides spaced apart gripping points to establish a pivot axis to correct for skew. The computer controls the coordinated movement of the sections to pivot and side shift the sheet to a desired position.
