Patent number: 8157143Abstract: 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.Type: GrantFiled: September 7, 2006Date of Patent: April 17, 2012Assignee: Heidelberger Druckmaschinen AGInventors: Holger Klamt, Siegmar Tischer

Patent number: 8123447Abstract: 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.Type: GrantFiled: February 14, 2006Date of Patent: February 28, 2012Assignee: Heidelberger Druckmaschinen AGInventors: Lutz Richter, Siegmar Tischer

Patent number: 7988138Abstract: A gatherer stitcher for collating signatures made of paper, paperboard and the like, for stitching the collated signatures and for delivering the stitched signatures, includes a gathering section, a stitching station and a delivery station. The stitching station has a stitching carriage with at least one stitching head and, during a stitching operation, the stitching carriage is moved by a stitching carriage drive at a speed of the collated signatures. A switching unit is disposed between the stitching carriage drive and the stitching carriage for adapting a stitching carriage movement to a gatherer chain pitch, that is to say for adapting a horizontal reciprocating movement of the stitching carriage, and for adapting a horizontal distance between the stitching carriage and the delivery station.Type: GrantFiled: May 18, 2009Date of Patent: August 2, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Torsten Brünner, Frank Jaentschel, Torsten Krause, Andreas Steinert, Siegmar Tischer

Patent number: 7762538Abstract: A gatherer stitcher includes an endless gatherer chain for gathering and transporting folded sheets astride the chain. The gatherer chain has chain roof segments and driving elements being adjustable in position. In an inactive position, a driving element that can be folded forms part of the roof of the gatherer chain and, in another, active position, projects out of the roof of the gatherer chain transversely relative to the conveying direction.

Patent number: 7637489Abstract: A stitching apparatus for manufacturing printed products, in particular in a gathering and stitching machine, includes a stitching carriage, at least one stitching head for shaping and driving a staple into a stack of signatures, and at least one clinch box for closing the staple driven through the signatures. An actuating device vertically displaces the stitching head for adaptation of the stitching apparatus to a thickness of the stack of signatures. A gathering and stitching machine having a stitching apparatus is also provided.Type: GrantFiled: September 19, 2006Date of Patent: December 29, 2009Assignee: Heidelberger Druckmaschinen AGInventors: Torsten Brünner, Siegmar Tischer

Patent number: 7628389Abstract: 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.Type: GrantFiled: May 4, 2005Date of Patent: December 8, 2009Assignee: Heidelberger Druckmaschinen AGInventors: Andreas Steinert, Siegmar Tischer

Patent number: 7520496Abstract: A driver element is provided for an endless saddle chain in a saddle line, wherein the saddle chain includes saddle segments and receiver segments, with the saddle segments defining a substantially saddle-shaped roof of the saddle chain. The driver element is arranged to be detachably fastened without tools to a respective one of the receiver segments. The driver element includes two driving flaps that are pre-tensioned against each other.Type: GrantFiled: August 11, 2006Date of Patent: April 21, 2009Assignee: Heidelberger Druckmaschinen AktiengesellschaftInventors: Klaus Kinne, Siegmar Tischer

Patent number: 7451969Abstract: 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.Type: GrantFiled: May 4, 2005Date of Patent: November 18, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Rolf Böttcher, Lutz Richter, Andreas Steinert, Siegmar Tischer

Patent number: 7337937Abstract: A stitching apparatus for manufacturing stitching wire staples, in particular annular eyelet staples, for stitching stacked sheet materials, includes a stitching head basic body having a driver for driving the stitching wire staples into the stacked sheet materials in a downward movement of the driver. A former shapes the stitching wire staples, in particular annular eyelet staples. The former is pivoted away during the downward movement of the driver. A wire clamping lever is mounted pivotably in the former. The wire clamping lever has a control element which runs on a control cam in such a way that the former is supported as a result in the upward movement of the driver, with the result that the former is pivoted-in in the upward movement to a different point than the pivoting-out of the former in the downward movement.Type: GrantFiled: September 19, 2006Date of Patent: March 4, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Holger Klamt, Siegmar Tischer
