Abstract: A continuous paper feeder for supplying sheets of paper to a receiving machine from a top of a first stack of paper while being resupplied to a bottom of the first stack of paper with sheets of paper from a top of a second stack of paper. A concave paper hopper maintains a generally constant angle of incidence of a leading edge of sheets of paper from the top of the first stack of paper to a picker of the receiving machine. Sheet feed belts transfer paper from the top of the second stack of paper to the bottom of the first stack of paper while sheets of paper are continually removed from the top of the first stack to the receiving machine by the picker.

Abstract: For use in transporting a packet containing from one to a plurality of pages, a dynamic roller positioning system for adjusting a packet receiving gap between two rollers. Comprising the system is a pair of rollers with each roller having a packet contacting surface and the packet receiving gap separating the surfaces, gap setting actuators for setting the paired rollers by steps to a selected gap dimension, and a control system for setting the actuators for the number of pages in each packet.
