Abstract
A belt conveyor leads past a processing station. Printing products lie on the conveyor belt in an imbricated formation, each printing product lying on the preceding one with edges to of the printing products running at an angle to the conveying direction of the belt conveyor. As a result of this incline, the printing products are exposed in a surface region and in the sections of the edges. Printing products are acted upon mechanically in the work station in these exposed regions. Individual printing products are thus taken up in a trouble-free manner and detached from the imbricated formation.
Claims9
A method for processing a plurality of printing products conveyed in a conveying plane by a conveyor moving the plurality of printing products in a conveying direction through a processing station, each printing product having a first surface facing the conveyor and a second surface opposite the first surface, the method comprising the steps of:
- feeding the plurality of printing products in the conveying direction through the processing station in an inclined imbricated formation in which all edges of each printing product are inclined at an acute angle to a line orthogonal to the conveying direction to define an uncovered edge region for each printing product that is not covered by an adjacent printing product;
- exposing the first and second surfaces of lateral corners of the edge region for each printing product, the lateral corners extending beyond lateral edges of the conveyor;
- processing a selected one of the plurality of printing products in the processing station by extracting the selected one of the printing products from the inclined imbricated formation by acting on one lateral corner to move the printing product in a direction transverse to the conveying direction;
- and
- maintaining the extracted printing products in the conveying plane and the unextracted printing products in the inclined imbricated formation during said processing step.

- feeding the plurality of printing products in the conveying direction through the processing station in an inclined imbricated formation in which all edges of each printing product are inclined at an acute angle to a line orthogonal to the conveying direction to define an uncovered edge region along selected first and second edges for each printing product that is not covered by an adjacent printing product;
- exposing the first and second surfaces of lateral corners of the edge region for each printing product, the lateral corners extending beyond lateral edges of the conveyor;
- mechanically influencing the plurality of printing products in the processing station by selectively applying information to either one or both of said selected first and second edges of the uncovered edge regions of the plurality of printing products;
- and
- maintaining the printing products in the conveying plane and in the inclined imbricated formation during said mechanical influencing step.
