ABSTRACT:
The apparatus for changing the position of printed products arranged in an imbricated formation comprises two band conveyors arranged in tandem as viewed in the conveying direction, and a position-change device arranged in the end region of the conveying-active path of the first of the two band conveyors. The disc-shaped supporting elements of the position-change device and each having a cam are seated at shafts, the rotational axes of which extend substantially perpendicular to the plane of conveyance of the first of the two band conveyors. The shafts are driveable synchronously and in opposite directions. The trailing or upstream edges of the printed products come to bear upon the disc-shaped supporting elements and the cams upwardly project in the region of the imbricated formation. During each revolution of the disc-shaped supporting elements the cams bear against the trailing or upstream edge of a printed product, entrain the printed product in the conveying direction and deliver the printed product to the second of the two band conveyors. The position of the printed products is changed in the imbricated formation such that the spacing or pitch between the trailing or upstream edges of the printed products outfed by the second of the two band or belt conveyors is constant.
