ABSTRACT:
A sheet feeder for dealing with simplex or duplex copy sheets from a copier or like reprographic machine uses four rollers forming three sheet-feeding nips. All sheets enter the central nip: on leaving it they are selectively diverted into one or other of two sheet pockets, from which they bounce or are otherwise fed back into an aligned other nip. Sheets passing through one outer nip may be fed to an output tray, while those passing through the other nip may go back into the machine for further processing.
