  • Patent number: 4871163
    Abstract: A paper control gate directs a sheet from any one to any other of a plurality of three or more stations angularly disposed about a single rotatable shaft mounting one or more vanes. The vanes are in general curved and deflect a sheet through an appreciable angle. Where there is little or no sheet deflection between stations, a pair of parallel vanes may provide a passageway. The vanes may be flared at each end to accommodate reversible sheet paths. Large shaft rotations are employed. The stations are equally spaced from the shaft and each is provided with a frictional sheet drive roller.
