ABSTRACT:
A sheet feeding system for feeding single sheets from a magazine containing plural sheets arranged in a stack. A vacuum type sheet pick-up mechanism picks up and deforms one end of the top most sheet to facilitate that sheets separation from the stack. Static and movable separators then act on the top most sheet to complete its separation from the stack and elevate the leading edge to bring it into contact with a friction drive mechanism. The friction drive mechanism is then activated by an external device to cause the sheet to be driven from the magazine. A programmed logic control system sequentially controls the cycling of the mechanism.
