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.
Claims23
A sheet gate including in combination a rotatable shaft, a plurality of at least three stations angularly disposed about the shaft, vane means for directing a sheet along a path from any of said stations to any other of said stations, said vane means including a plurality of vanes mounted on the shaft, said pair of vanes including closely spaced and generally parallel portions defining a passageway therebetween, and means for rotating the shaft to a plurality of angular positions at each of which the vane means is operative to permit movement of a sheet from one of said stations to another of said stations.
A sheet gate including in combination a rotatable shaft, a plurality of at least three stations angularly disposed about the shaft, vane means for directing a sheet along a path from any of said stations to any other of said stations, said vane means including at least a first vane mounted on the shaft, and means for rotating the shaft to a plurality of angular positions at each of which the vane means is operative to deflect a sheet from one of said stations through an appreciable angle to another of said stations.
