摘要:
A web-fed printing press is disclosed. The press having at least one printing unit for printing at least one printing substrate web, and having at least one processing device for processing the at least one printing substrate web, a control device for controlling the at least one processing device, and a fastening device for arranging the at least one processing device at an arbitrary web feed position between a reel changer of the web-fed printing press and an exit of a folding unit of the web-fed printing press in such a way that the at least one processing device is able to process the printing substrate web on an upper side and/or on a lower side and/or on one or both edges of the same.

The invention pertains to a device for processing printed matter, in particular, for punching, perforating, grooving, embossing, imprinting, spot-coating or the like. In order to simplify the attachment of the processing tools required for the additional processing, the invention proposes that a carrier be attached to a rotating or flat working element 8. The processing tools can be attached to this carrier such that they can be easily removed again. The size of the processing tools 3 that, for example, are provided with punching lines 4 can be limited to the processing area. The processing tools can be removed and also easily repositioned at any time. A magnetic attachment proved particularly advantageous. For this purpose, the carrier may be realized in the form of a magnetic foil 6.

The invention relates to a perforating, grooving or cutting device for a multicolor or single-color sheet-fed rotary press (1) comprising printing and/or varnishing groups (2), at least one of which has a rubber cylinder (3) with a holding system (14) for a blanket, as well as an associated counter-pressure cylinder (4). According to the invention, a rectangular base plate (13) is provided, which is made from a flexible and shape-retaining material over which it is possible to glue embossed treatment profiles (29, 37) used as perforating and/or grooving and/or punching profiles corresponding to perforating and/or grooving and/or punching shapes which can be predetermined. Furthermore, at least two fastening strips (17, 18) are provided for detachably attaching the punch foil to opposed marginal areas in the stretched state.

In a rotary printing press with a blanket cylinder (2) and an impression cylinder (3), the blanket is removed and replaced by a base sheet (5). On this base sheet (5) are arranged strips (6). The arrangement of the strips (6) corresponds to the perforation, stamping or creasing to be produced in the paper or cardboard passing through the rotary printing press. On the impression cylinder (3) is arranged a smooth protective sheet (7). Both sheets (5) and (7) can be used several times and can be installed or removed rapidly by means present on the machine.

In some examples, a processing machine for processing a substrate includes at least one shaping unit. The at least one shaping unit includes at least one forme cylinder and at least one impression cylinder. A processing point for processing a substrate is arranged between the at least one forme cylinder and the at least one impression cylinder. The processing machine includes a control unit for correcting a processing length of the substrate, and which controls a speed of at least one of the at least one forme cylinder or the at least one impression cylinder. The at least one forme cylinder and the at least one impression cylinder have a speed ratio with respect to one another that is changeable at the processing point as a function of the processing length of the substrate, and the speed ratio differs at least once within a full cylinder revolution.

A process for recycling a transfer film (1) and a transfer film (1) suitable for this having a carrier film (2) and a transfer ply (4) arranged at least partially on the carrier film (2), wherein a detachment layer (3) is arranged between the carrier film (2) and the transfer ply (4), and wherein the transfer ply (4) has an alkali-soluble topcoat (5), wherein the topcoat (5) is arranged on the detachment layer (3), and wherein the following step is carried out in the process:
x) dissolving (10) the alkali-soluble topcoat (5), in particular the alkali-soluble binder of the topcoat (5), by means of an alkaline washing liquid (9), preferably in a washing liquid bath, wherein the transfer ply (4) is detached from the carrier film (2).
摘要:
A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.

The present invention relates to a device for treating substrates which device is modular and versatile in use. The device for treating substrates comprises a feeder and one or more first sub-structure modules which each comprise a pressure cylinder with devices for fixing a lift and a sheet-conveying device and one or more second sub-structure modules which respectively have a transport cylinder with openings formed on the cover surface thereof, and having devices for fixing a lift and a sheet conveying device. All of the first or second sub-structure modules have the same intersection point for connecting the sub-structure modules on one of the inlet and the exit side and they all can be equipped with an attachment module.
