Abstract: A stitching device for producing stitching wire staples for stitching stacked sheet materials, includes a stitching head base body and a cutting box fixed to the stitching head base body. The cutting box includes a movable knife slide. A control device controls the movement sequences of the stitching head, in particular of the knife slide, for cutting off the stitching wire automatically. The stitching head base body, the cutting box and the knife slide are configured in such a way that, during interaction, the movable knife slide can be displaced relative to the stitching base body in order to cut off the stitching wire. The cutting box and the knife slide are provided with at least partly aligned openings in such a way that, during interaction between these openings and an operating device, it is possible to cut the wire off manually.

Abstract: A method for backing printed products includes feeding signatures to a transport and stitching line of a gatherer stitcher by a plurality of feeders. A plurality of signatures are gathered on the transport and stitching line and forms a folded sheet assembly. The folded sheet assembly is stitched to form a brochure along the transport and stitching line. The spine of the brochure is backed along the transport and stitching line by a pressing apparatus.

Abstract: A gatherer stitcher for brochures has a stitching machine, a delivery station that receives brochures step-by-step during operation, a trimming apparatus, and transport components (brochure ejector, trimmer feed) that transport the brochures from the delivery station to the trimming apparatus during operation. Sensors assigned to the stitching machine and the transport components output signals defining their phase position, and a control system processes the signals. One of the transport components (brochure ejector; trimmer feed) is activated in such a way that the brochures assume a correct position in the trimming apparatus at a predetermined phase angle of the stitching machine, without regard to their width. Changeover times in the event of job changes required when the brochure width changes are shortened.

Abstract: To optimize the effort involved when converting a gatherer stitcher which transports initially continuously transported brochures step by step into a stitching station and subsequently into an output station, sensors are assigned to machine components affected by geometrical parameters that are relevant to the process when there is a change of job order and to a reference component. The sensors emit signals defining the phase positions of the machine components, and a controller processing the signals coordinates the phase positions with at least one of the parameters in such a way that the brochures arrive in the output station in a center-oriented manner.

Abstract: A gatherer stitcher having a gatherer chain configuration includes roof segments forming a ridge region and drivers having respective stop surfaces and being mounted so as to be adjustable between an operating position and a position pivotable away therefrom. An auxiliary driver is restricted to the ridge region and carried by a respective roof segment directly adjacent the stop surfaces. The auxiliary driver, in the operating position of the adjustable driver, forms a combined stop surface together with the adjustable driver.

Abstract: A stitching device includes at least one stitching station having an inlet region and an outlet region, and a transport device for conveying a plurality of folded signatures to the stitching station through the inlet region for stitching the plurality of folded signatures and for conveying the stitched plurality of folded signatures away from the stitching station through the outlet region, and further including a guide element for supporting the plurality of folded signatures during transport thereof through at least one of the inlet and the outlet regions; and a gathering-stitching device including the stitching device.

Abstract: The gathering stapler has a number of individual subassemblies, including a stapling carriage, a collecting chain, a stapling-displacement configuration, a delivery, and an ejector. Each of these subassemblies has a dedicated drive. Controllable motors are provided as the power sources. It is thus possible to synchronize the movements of the respective subassemblies and to alter the speeds of the movement during a machine cycle. In particular, synchronization of the movement of the simultaneous operation of the stapling carriage, of the stapling-displacement configuration and of the collecting chain is carried out such that for individually adjacent cycles, at different points in time, the product and stapling carriage have adapted speed profiles. As a result, it is possible to carry out a stapling operation at different positions on the product.
