A tri-directional inverter for use in machines requiring copy sheet inversion for collated copy set output uses four rollers forming three sheet-feeding nips. All sheets enter the center nip and contact a diverter gate that urges them in either of two directions. The sheets are corrugated by corrugating rollers as they enter a spring loaded inversion channel. The spring and corrugation rollers urge the sheets back out of the inversion channel into engagement with either of the selected other nips formed by the four rollers for feeding back into the machine for further processing.

Four roll inverter

A magnetic roll which is used in a processing station of an electrostatographic printing machine. The roll has a central portion with a plurality of spaced fins extending generally radially outwardly therefrom. A shaft extends outwardly from opposed ends of the central portion along the longitudinal axis thereof. A magnet is secured in each space between adjacent fins. A sleeve is rotatably supported on the shaft.
