A method and apparatus for producing selectively collated print products employ a production section, a control device, a transfer-out device for transferring out defective print products, a detection device that detects and records gaps resulting from the transfer out of defective print products, and a transfer-in device. Initially, a line of print products are processed in a production section; a predetermined number of print products are diverted from the production section and supplied to a product buffer. If the print products are not diverted, the line of print products continue in a conveying section and gaps between the print products are detected and recorded via the detection device. A number of print products are removed from the product buffer based on a control signal from the control device to fill detected gaps between print products in the conveying section; and the removed print products are inserted into the recorded gaps.

Method and apparatus for producing selectively collated print products

An apparatus for processing folded printed sheets includes a work station for processing the folded printed sheets and a conveying device driven with a transporting movement in a direction along a conveying path that is arranged alongside the work station. Saddle-shaped supports are attached to the conveying device and have supporting edges on which the printed sheets can be supported respectively along their fold by straddling the supporting edge of the respective saddle-shaped support. The saddle-shaped supports are conveyed along the conveying path so that the supporting edges are positioned transverse to the conveying path at a distance to each other and move successively past the work station which cooperates with the saddle-shaped supports respectively while the saddle-shaped supports are transported past the work station. A mechanism movably attaches the saddle-shaped supports on the conveying device and guides the respective supporting edges along a movement path in which, in a region of cooperation with the work station, a relative speed component of the supporting edges parallel to the conveying path, with respect to the work station, is smaller than a relative speed for the transporting movement of the conveying device.
