ABSTRACT:
A high speed sheet feeder for use with utilization devices that process sheets comprises a source of sheets, that can include a web cutter and a transport unit having a surface along which the sheets travel in a downstream direction. The surface can include a pair of conveyors that act as sheet justifiers and have at downstream ends thereof wait stations that can comprise pairs of nip rollers. Sheets are halted at each wait station and simultaneously passed along the surface as a sheet request signal is received from the utilization device. The transport unit can further include a bump/turn module that receives sheets from the conveyors and passes them at 90.degree. angle to their initial direction of travel into the utilization device via a port in the utilization device adapted to feed sheets upon request.
