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.

Dependent claims

An apparatus for changing the position of printed products such as newspapers, magazines and the like, arranged in an imbricated formation, comprising:

a conveying device defining a plane of conveyance for the imbricated formation;
at least one position-change device provided with a plurality of revolvingly driven entrainment members which pass through at least one closed revolving path;
said conveying device having a predetermined conveying speed and a predetermined conveying direction;
said at least one position-change device having a predetermined rotational speed which is greater than said predetermined conveying speed of said conveying device;
said plurality of revolvingly driven entrainment members acting upon trailing edges of the printed products as viewed in said predetermined conveying direction;
said plurality of entrainment members comprising at least two entrainment members;
said at least one closed revolving path comprising at least two closed revolving paths substantially arranged in said plane of conveyance;
said at least two entrainment members revolving synchronously to one another along said at least two closed revolving paths in order to act in pairs upon the trailing edge of each printed product;
said at least two closed revolving paths having portions in which said at least two entrainment members can be brought to act upon the printed products;
and
said portions of said at least two closed revolving paths being arranged in spaced relationship in a direction substantially perpendicular to said predetermined conveying direction of said conveying device.
