Abstract: In a method for producing folded printed products a paper web is printed by at least one digital printing machine and the paper web is then processed by a sequence of processing steps, wherein full size sheets or web sections having at least four printed pages for a printed product with a multiple of four printed pages are cut from the paper web. The full size sheets or web sections are then folded to a folded state, respectively. The full size sheets or web sections are collected in the folded state and subsequently stitched. A buffer is formed of the full size sheets or the web sections during the sequence of the processing steps and the full size sheets or the web sections coming from the buffer are individualized to decouple the digital printing machine from at least some of the processing steps.

A measuring device measures a position of each of the printed products in the first cutting station before reaching a cutting position. A control device controls the transport device based on the position measured by the measuring device such that a deviation of the position measured by the measuring device from a nominal position is corrected during further transport of the printed products.
Abstract: A feeder for collecting printed sheets in an astride position includes a pulling-off drum which has at the circumference thereof gripping members for pulling off printed sheets stacked in a magazine. The feeder further includes a unit for conveying the printed sheets with an open side facing forward into an opening device. The opening device is arranged in front of a collecting device. The unit arranged between the pulling-off drum and the opening device is formed by a pocket wheel or a pocket chain provided with revolving pockets for receiving the printed sheets which are supplied with their folds facing forwardly, and a conveying member arranged in front of the pockets.
Abstract: A feeding device for feeding a processing line with printed products, including folded or non-folded printed sheets, from a stack of printed products. The printed sheets are held in a magazine. A conveyor defines a circulating path and moves in a conveying direction for conveying the printed products to the processing line. A synchronously driven separating mechanism, which is pivotally attached to the magazine, acts upon a closed fold or an edge of the printed product and operates to partially remove the printed product from the stack of printed products. A gripping arrangement includes a controlled gripping device attached to the conveyor in a feeding region of the processing line and essentially moves along in the conveying direction for taking over the printed product from the separating mechanism by gripping a front edge of the printed product relative to the conveying direction.
Abstract: A feeder device for removing folded or unfolded signatures from a stack of signatures in an adjacent signature magazine and feeding a production line with the signatures. The device includes a conveying rotor having an approximately circular circumference and being rotatable in a conveying direction. The conveying rotor includes a recess at the approximately circular circumference for holding a front edge, in the conveying direction, of a printed product removed from the stack of signatures. A conveying belt partially rests against the circumference of the conveying rotor, and is drivable in the same direction as the conveying rotor, and together with the conveying rotor forms a conveying gap through which the signatures are conveyed to the processing line. At least one synchronously driven separating element includes a control device comprising a pivotal control shaft arranged parallel to the rotational axis of the conveying rotor.
Abstract: An arrangement for stitching the spine of printed products, complied of folded printed sheets, by staples has a stitching device with a stitching head/bending arrangement. A conveying device for conveying the printed products to the stitching device at a spacing sequentially behind one another and with the spine transverse to the conveying direction is provided. The stitching device has a stitching support on which the stitching head/bending arrangement is arranged. The stitching support is configured to move during the stitching process approximately in the same direction and at least approximately at the same speed as the conveying device.
Abstract: In a method for adhesive attachment of a cover and a binding strip on the flanks of a spine of an book block comprised of bound printed sheets, the book block is transported in a transport direction on a circulating transport device. A binding strip is placed onto the book block spine such that lateral strip parts project laterally past the spine. The cover is moved into a proper position relative to the book block spine in accordance with the cycle of the book block and in the transport direction of the book block. At least one of the lateral strip parts is loaded on a side facing away from the cover with a pressing element. The cover and the book block pass through a pressing device in order to connect the cover and the book block to one another.

Abstract: A device is used to insert and/or deposit printed products into a conveying channel. The printed products are conveyed in the conveying channel with of carriers of a conveying element. An acceleration apparatus pre-accelerates the printed products in conveying direction. The acceleration apparatus conveys the printed products essentially in a straight line and at an angle to the conveying direction of the conveying channel. The printed products are preferably inserted with the aid of conveying belts and at an angle into the conveying channel. As a result of the slanted feed, the divisions of the conveying element can be optimized and the capacity increased.
Abstract: A device for removing printed products, having a fold and being transported uniformly spaced and astraddle by a transport device, has a rotatingly driven gripping device with controlled gripping elements for gripping one of the printed products by the fold on the transport device and removing the printed product while stably holding the printed product. The rotatingly driven gripping device has control elements for controlling an opening movement and a closing movement of the gripping elements and is adjustable for adaptation to the different thicknesses of the printed products during running.
Abstract: A conveying device for collecting and transporting printed sheets has a first chain conveyor on which the printed sheets are placed astraddle to be conveyed in a conveying direction. A second chain conveyor is arranged downstream of the first chain conveyor in the conveying direction and synchronized with the first chain conveyor.
