Abstract:
A gripper drum for gripping printed products includes a drum shaft; at least one gripper disk coupled to the drum shaft; a gripper shaft disposed on the at least one gripper disk and having a shaft body rotatable about its longitudinal axis; an apparatus for controlling the gripper shaft; and a plurality of grippers disposed on the shaft body. The grippers are adaptable to be rotated about the longitudinal axis of the gripper shaft for gripping the printed products. The gripper drum further includes a tensing apparatus coupled to the gripper shaft for compensating any play between the controlling apparatus and the plurality of grippers. The gripper drum operates to define an opening movement and closing movement of the grippers.
Abstract:
In a method for at least partially cycle-dependent manufacturing of bound printed products by adhesive binding printed sheets in a spine area of an book block or by stitching with staples folded edges of printed sheets collected astraddle, a sequentially double-sided digitally printed paper web or individual sheets are transversely cut to from the printed sheets. The printed sheets are then transversely folded and subsequently supplied either to an adhesive binding station or to a saddle-shaped conveying support for stitching with staples.
Abstract:
In a method for manufacturing a printed end product containing a single printed product or several printed products, collected astraddle and supplied sequentially, and bound by stitching, the printed products are collected in a predetermined sequence required for forming the printed end product along a common conveying path. Subsequently, the printed products are stitched. A circulating collecting support is provided which is supplied by a feeding device with spread-apart printed products. After the collecting step is complete, the collected printed sheets are moved on the conveying path to the stitching location.
Abstract:
A device for collecting printed sheets in a certain sequence astride and atop one another to form a printed product has a saddle-shaped support supplied by a sheet feeder with printed sheets. The saddle-shaped support is arranged above a conveying device transporting the printed products to a further processing step. The saddle-shaped support has a circulating traction mechanism and driving members connected to the circulating traction mechanism. The driving members act on the printed products to convey the printed products in a direction parallel to a conveying direction of the conveying device.
Abstract:
A device for producing bound printed products has a continuous folding device to which are supplied sequentially individual printed sheets and in which the printed sheets are folded individually to folded printed sheets. A gathering device receives the folded printed sheets from the continuous folding device and gathers them in a predetermined number to a pre-product in a position in which the folded printed sheets are astraddle. A transport device is arranged downstream of the gathering device and receives the pre-product from the gathering device. The gathering device has at least one blade extending substantially parallel to the transport direction of the transport device. The folded printed sheets are gathered on the blade to form the pre-product. A device for moving the at least one blade in the transport direction is provided.
Abstract:
A perfect binder for processing book blocks, including: a conveying device adapted to convey the book blocks along a closed circulating path, the conveying device including a plurality of clamping devices each adapted to convey a book block; and a plurality of processing stations arranged successively along the closed circulating path. One of the processing stations includes a spine-processing station, and another one of the processing stations includes an end sheet feed station following the spine-processing station.
Abstract:
A method for manufacturing a printed product formed from a plurality of printed sheets which are printed sequentially for processing, wherein the printed products each comprise at least one printed sheet and an additional sheet which are stacked together in a stacking apparatus. The method includes feeding the additional sheet to the at least one printed sheet on a conveying path of a first conveying apparatus to the stacking apparatus.
Abstract:
A wire-stitching apparatus for producing wire-stitched print items includes a conveying arrangement for supplying folded, printed products in a straddling position; a wire-stitching unit installed at an adjustable distance above the conveying arrangement and including a bending device; at least one wire-stitching aggregate; and a stitching carriage for moving the at least one wire-stitching aggregate back and forth along a path. The wire-stitching aggregate includes a bender for forming legs of a staple and a driver for pushing the staple legs through the printed products. At least one wire feed feeds wire to the one wire-stitching aggregate at a stitching wire length. At least one adjustable wire-cutting device for adapts a wire staple to the thickness of the printed products. A control unit measures the thickness of the printed products positioned on the conveying arrangement upstream of the wire-stitching unit, and/or processes stored data related to the printed products.
