Definitions

  • the invention relates to a device for transferring imaging layers from a carrier film to printing sheet according to the preamble of patent claim 1.
  • EP 0 569 520 B1 describes a printing material and a printing device using this material.
  • a sheet-processing machine which has a feeder and a boom, between two units printing units and a coating unit are arranged.
  • an adhesive pattern is applied by means of the planographic printing process. This adhesive pattern is applied in a cold printing process and has a specific imaging subject.
  • a film guide is provided in the printing unit following the coating unit with a counter-pressure cylinder and a press roller.
  • the transfer film has a carrier layer on which imaging layers such as metallic layers, for example of aluminum, can be applied. Between the metallic layer and the carrier film, a separating layer is provided, which ensures that the metallic layer can be removed from the carrier layer.
  • each sheet is given an adhesive pattern.
  • the sheet is passed through the coating unit, being brought by means of the press roller on the impression cylinder resting sheet with the film material in combination.
  • the downwardly lying metallic layer enters into a close connection with the areas provided with adhesive on the printed sheet.
  • the carrier film is thus removed from the metallic layer in the region of the adhesive pattern.
  • transfer film is wound up again.
  • the print sheet is laid out in the coated state. It is known to use such coating units, for example in printing units of printing presses. A disadvantage of the known devices is that they are not flexible and that the consumption of transfer film is expensive.
  • the object of the invention is therefore to provide a device by means of which the transfer of an imaging layer, e.g. a metallization layer on a sheet can be done safely, economically and accurately, the device should be easy to handle.
  • an imaging layer e.g. a metallization layer on a sheet
  • a multi-web method is used for guiding the transfer film, in which the transfer film can be driven by a common drive during feeding to the transfer nip in partial film webs.
  • An associated device for feeding the transfer film advantageously has one or more independent storage devices for receiving one or more sub-film rolls, by means of which the unwinding of partial film webs during the supply to the transfer nip is made possible.
  • a further improvement of the film utilization results from the fact that the transfer film is divided into one or more Partfolienbahnen smaller width. In combination with the above-mentioned method, it is thus also possible to use different types of film side by side.
  • a control of the transfer film can be carried out such that, when passing through a cylinder channel receiving the grippers of the sheet-guiding impression cylinder, the film feed is stopped, wherein the press roll then passes in a sliding manner under the transfer film.
  • the image-forming layer can be applied by means of so-called UV negative-pressure ink.
  • the UV negative pressure ink is applied by means of the printing unit for the adhesive in a corresponding manner via an offset printing plate.
  • the application of different imaging coatings or metallization layers within a subject can take place one after the other.
  • the transfer nip 6 in the coating unit 2 is formed by a press roll 3 and an impression cylinder 4.
  • the press roller 3, the blanket cylinder and the impression cylinder 4 correspond to the impression cylinder of an offset printing unit.
  • the press roller 3 can correspond to the forme cylinder and the impression cylinder 4 to the impression cylinder of a paint module of a sheet-fed press.
  • downstream of a so-called calendering be provided.
  • the transfer films 5 have a multilayer structure. They have a carrier layer on which an imaging layer is applied by means of a release layer. The separating layer serves to facilitate lifting of the imaging layer from the carrier layer.
  • the image-forming layer may be, for example, a metallized layer or a glossy layer or a texture layer or a colored layer or a layer containing one or more image patterns.
  • the film supply roll 8 is assigned to the coating unit 2 on the sheet feed side.
  • the film supply roll 8 has a rotary drive 7.
  • the rotary drive 7 is used for the continuous controlled feeding of the transfer film required for the coating unit 2 and is therefore controllable.
  • a deflecting or tensioning roller is provided in the region of the film feed.
  • the film web of the transfer film is always held in the same voltage against the press roller 3.
  • a film collection roller 9 is shown on the downstream side of the printing unit.
  • the used film material is wound up again.
  • a rotary drive 7 is provided for the optimized production, which is controllable.
  • the transfer film 5 could also be moved by the rotary drive 7 on the discharge side and kept taut on the inlet side by means of a brake.
  • the transfer process of the imaging eg metallized layer on the printing paper takes place in the transfer nip 6 between the press roller 3 and the impression cylinder.
  • the press roll 3 may be a blanket cylinder of an offset printing unit.
  • the press roll 3 can also be the forme cylinder of a paint module. It is essential that the surface of the press roll 3 so the blanket cylinder or forme cylinder is equipped by means of a compressible, damping element.
  • the press roll 3 can be provided with a press fabric, for example as a plastic coating, comparable to a blanket or blanket.
  • the press fabric is held in a cylinder channel on jigs.
  • the press fabric is equipped to improve the transmission properties in the transfer nip 6 with a targeted elasticity. This may optionally act in a compressible intermediate layer.
  • This compressibility is preferably similar or less than in conventional blankets or blankets, which can also be used at this point.
  • the mentioned compressibility can be produced by means of a conventional compressible printing blanket.
  • combined fabrics made of a hard blanket and a soft pad can be used.
  • a limited pressing surface can be provided directly on the press roll 3 or on the press fabric. This can be worked out of the surface of the press fabric or it can be additionally attached as a partial surface of the material of the press fabric on the press roller 3.
  • the film advance of the transfer film from the film supply roll 8 to the transfer nip 6 and the film collection roll 9 is controllable such that the transfer film 5 is stopped as far as possible if no transfer of the image-forming layer is to take place:
  • a control of the transfer film 5 can be made such that the film feed is stopped when passing through a gripper of the sheet-guiding counter-pressure cylinder 4 receiving cylinder channel.
  • the grippers hold the printed sheet on the impression cylinder 4.
  • the press roll 3 has a cylinder channel. In the region of the cylinder channel, there is no pressing of the transfer film 5 between the press roller 3 (blanket cylinder) and the impression cylinder 4, since both cylinders have this cylinder channel.
  • the press roll 3 then slidably passes under the transfer sheet 5, while the transfer sheet 5 between the press roll 3 and impression cylinder 4 is freely stretched. This state continues until at the so-called pressure beginning of the cylinder channel ends and the transfer film 5 is again clamped between the press roller 3 and the impression cylinder 4, including a sheet. Then, the transfer sheet 5 is further transported.
  • the timing of the film feed can begin or suspend slightly earlier than pretend the channel edges of the cylinder channel according to a necessary acceleration or braking of the film supply roll 8 or film collecting 9.
  • the associated device basically includes a corresponding feed control for the transfer film 5, which ensures that at least the foil piece lying between the press roller 3 and the impression cylinder 4 is stationary as long as the cylinder channel passes through.
  • a further improvement of the film utilization of the type described results from the fact that the transfer film 5 is divided into one or more Operafolienbahnen lesser width. This can with appropriate control with the help the device or devices for timing the film feed each of the sub-film webs, the utilization of the transfer film 5 are improved even in zonally different lengths coating areas within an arc.
  • each partial film web is conveyed only exactly in the area where the imaging surface layer is to be applied. In the areas not to be coated, each partial film web can be stopped independently of the other partial film webs, whereby no unnecessary film consumption arises.
  • the object of the invention is to enable the delivery of either a full-sized parent roll, i. a transfer film roll with maximum film width or - to save on film material - also the possibility that several narrower single roles may be different width and different diameters can be processed.
  • FIG. 1 a device for guiding a plurality of narrow film webs, each with the same speeds, is shown in FIG.
  • an unwinding shaft 14 for receiving the film supply roll 8 is arranged in connection with the roller drive 7.
  • This unwinding shaft 14 can be designed as an expansion unwinding shaft.
  • the unwinding shaft 14 is replaced by a rubber roller 16.
  • the rubber roller 16 is connected to the drive 7 as well as the unwinding shaft 14.
  • Parallel to the rubber roller 16 one or more bearing arms 15 are provided.
  • the bearing arms 15 are adjustable on the pivot axis 17 to the required different distances from one another. By means of its guidance on the bearing arms 15, the partial film rolls 13 can be applied against the rubber roller 16.
  • the guidance of the individual partial film rolls 13 on the bearing arms 15 with respect to the rubber roller 16 can be ensured in the simplest way under the action of the own weight of the partial film rolls 13.
  • the bearing arms pivot 15 - the sub-film rolls 13 against the rubber roller 16 continuously tracking - about its pivot axis 17.
  • the sub-film rolls 13 put on the rubber roller 16 in consequence of their weight with its circumference and are frictionally guided by the drive 7 of the rubber roller 16.
  • a so-called friction shaft can be used.
  • Such a friction shaft keeps the partial film webs 19 each under a preselectable tension, wherein the roller drive 7 possibly adjusts a leading speed, which is compensated by a slip within the friction shaft. In this way, in each case the correct web tension or the correct winding moment for the respective partial film web 19 is established.
  • edge-guiding elements for example edge-guiding elements
  • Flange wheels be provided so that the unwinding and winding of the partial film webs 19 takes place smoothly.
  • the equipping of the bearing arms 15 with new partial film rolls 13 with unused transfer film 5 can be done by means of a lifting device or a feed hopper.
  • This automatic systems are conceivable that an automatic removal the spent roll carrier and an automatic insertion of the new partial film roll 13 allows. Only the threading of the respective new partial film web 19 must then be carried out by hand. However, the threading of a new partial film web 19 can also be facilitated by adhering the beginning of the new web to a running end of the old web. Here, a larger storage space is provided on the take-up.
  • auxiliary systems such as those used for web feeding in web-fed rotary printing presses.
