Abstract
A machine for processing documents has a document feeder adapted to selectively adjust document feed rate and interdocument separation. The document feeder has a feeder surface for feeding documents into the machine. There is a nip between the feeder surface and a separator surface. The end document of a stack is urged, singly into the nip and advanced therebeyond by the feeder surface. The separator surface restrains the remaining documents of the stack. A control adjusts the speed of the separator surface to be continuously variable and independent of the speed of said feeder surface, with the separator surface speed adjusted to optimize the document feed rate, optimize interdocument separation, and minimize damage to the documents being fed into the machine.
