Abstract

A method and apparatus are provided for processing documents in a path wherein the documents each have first and second ends. Some of the documents have the first end being the leading end, and others of the documents have the second end being the leading end. The documents are conveyed to a receiver. The documents with the first end leading are conveyed into one end of the receiver. The documents with the second end leading are conveyed into the other end of the receiver from the opposite direction. The documents in the receiver then all have the same end orientation in the receiver. Two documents may initially be fed one on top of the other between a rotating wheel and retard pad. This selectively retards one document against the pad until the other document has been fed further forwardly beyond the leading edge of the one document.
