ABSTRACT:
Apparatus for diverting selected sheets of a scalloped stream of paper sheets from a first horizontal path into a second path which is coplanar with an adjacent and parallel to the first path has two superimposed rollers movable about a vertical axis to and from operative positions above the first path, and a flap which is located upstream of the rollers and is pivotable to and from a position in which it diverts successive sheets into the nip of the rollers when the sheets enter the second path. The axes of the rollers make an oblique angle with the direction of advancement of sheets along the first path, and the speed at which the rollers are driven is such that the sheets approaching the nip cannot catch up with the sheet in the nip. The radius of curvature of the arcuate path of the rollers about the vertical axis, as well as the extent of movement of rollers along such arcuate path, is adjustable to ensure that the orientation of sheets remains unchanged during transfer from the first into the second path.
