Abstract: 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.

Abstract: A trimming apparatus for trimming a lateral edge a printed product includes a trimming table arranged to receive the printed product in a position ready for trimming. A trimming knife is configured to cut the lateral edge of the printed product during a cutting stroke, thereby creating cuttings separated from the print product. A removal device is provided for removing the separated cuttings. The removal device includes a collection region arranged behind the trimming knife to receive the separated cuttings during the cutting stroke of the trimming knife and a plurality of air nozzles located above the collection region.
