摘要:
An apparatus for producing a bound print item from unbound printed products supplied in a straddling position to be stitched with wire staples comprises a conveying device with a support that is slanted toward the side and consists of individual elements. The conveying device includes carriers for the synchronized transfer of the printed products to an intermediate conveyor that is installed upstream of a stitching section. The transfer region between the conveying device and the intermediate conveyor is provided with a side-mounted, synchronously operated support plate which has a recess along the circumference to which the carriers are allocated.

An apparatus for producing printed products such as books, magazines, brochures, catalogues or the like comprises several connected devices for the processing of printed sheets. The printed sheets are admitted with blast air via at least one air supply in order to change or maintain their position. At least two of the connected devices are respectively provided with at least one blower for generating blast air. The blast air can be used in the respective device. The blowers are connected to a control unit of the apparatus so that the blast air generated by the blowers can be controlled as needed.

An apparatus and method for the post-processing of successively following, sequentially printed sheets, includes a conveyor, a folding table, a folding sword, a folding roller pair, at least one pressing-down mechanism, and a machine control that is operatively connected to the folding sword and the pressing-down mechanism. The pressing-down mechanism includes at least one mechanical braking element which acts in the region of the back edge onto the top side of the printed sheet to be positioned on the folding table. The stationary folding sword includes a compressed-air device with at least one outlet opening for compressed air which is focused onto a folding roller gap. The folding table forms a gathering device for at least two successively following printed sheets. A sensor, arranged in a region of the conveyor, is operatively connected to the machine control and functions to detect the printed sheets, transported with the conveyor.

An apparatus and method for optional cross-folding of successively following, sequentially printed sheets on a first transport segment. A compressed air device comprises a first control element that is connected to a control unit for triggering or suppressing a compressed air blast from at least one exit opening in the compressed air device. A printed sheet is diverted into a second transport segment for the folding operation or a third transport segment for bypassing the folding operation. The latter empties downstream of folding rolls into the second transport segment at a joint segment point, at which a fourth transport segment adjoins in downstream direction. The third transport segment is longer than the second transport segment or can be operated at a lower speed than the second transport segment such that a first sequence of printed sheets successively following on the first transport segment is identical to a second sequence of the successively following printed sheets located on the fourth transport segment.

An infeed station has a carriage that is supported on a machine frame of the infeed station in a way that allows it to be moved laterally and a stack conveyor mounted on the carriage for conveying stacks from an infeed position to a transfer position, from which the stacks can each be removed by the stack gripper. The stacks can be centered in two stack chambers, which are arranged side by side on the carriage. A stop element supported on the carriage is assigned to each stack chamber and can be moved between a working position and a retracted position, such that in their working position, the stop elements project into the associated stack chamber in such a way that the stacks can be moved by the stack gripper from a forward holding position of the transfer position towards the stop elements and placed against the stop elements. The stacks positioned on the stop elements are gripped by the stack gripper between a finger and pressing means and conveyed to a pallet.

A method and device for stitching printed products with a stitching machine, which includes a stitcher head and a bending device, which travel concomitantly with each printed product as it is conveyed in a travel direction during the stitching operation. The bending device is positioned first in a first position, which corresponds to the thickness of the printed products and is a certain distance away from the stitcher head in the direction transverse to the travel direction. Before a printed product is introduced, its thickness is determined and compared with a predetermined limit value; and, if this limit value is exceeded, the bending device is brought into a predetermined second position, which is farther away than the first position from the stitching head. After the printed product has been introduced, the bending device is moved back into the first position, and the wire stitch is driven into the printed product.

A device for counting printed products of an imbricated stream includes a first measuring unit for detecting a printed product edge directed transversely of the conveying direction of the imbricated stream and with an evaluating unit which receives signals of the first measuring unit for counting the printed products. Therefore, it is the primary object to provide a device of the above-described type which facilitates a higher counting accuracy even in the case of irregular imbricated streams of products.
摘要:
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.
摘要:
A method of producing perfect-bound printed products formed from several printed products, includes feeding printed products, which are gathered to form loose book blocks, are fed by feeders, which are arranged along a conveying line and are driven at least approximately with synchronous timing, to a conveyance device that has receiving devices that follow one another at regular intervals, and are transferred by this conveyance device into a gluing machine. The gluing machine, which is arranged downstream of the conveyance device and also has a conveying function, is run until it is empty in the event of an interruption of a processing operation by discontinuing further feeding of printed products to the receiving devices of the conveyance device and further feeding of loose book blocks to the gluing machine while the gluing machine is emptying.
摘要:
A method for continuously joining at least two imbricated flows of flat printed products which are conveyed at equal speeds and spaced from one another, the method includes initially offsetting a first imbricated flow of flat printed products relative to a second imbricated flow of flat printed products so as to form a first lateral overlapping area of both imbricated flows, continuously lifting the printed products of both imbricated flows in the first lateral overlapping area until the lateral overlapping is eliminated, and lowering or dropping the printed products of both imbricated flows in the raised lateral overlapping area, so that partially a printed product of the first imbricated or the second imbricated flow comes to rest above the first or second imbricated flows above a printed product of the respectively other imbricated flow, whereby a single imbricated flow with a second overlapping area of the printed products is formed.
