Definitions

  • the invention relates to a sheet-fed rotary printing press with a device for laminating or laminating printed products according to the preamble of patent claim 1.
  • a cold foil transfer method for use in printing machines is disclosed.
  • a sheet-processing printing machine which has a feeder and a boom, wherein printing units and coating units are arranged between the two units.
  • 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 image-giving subject.
  • a film guide is provided in the printing unit following coating unit with a counter-pressure cylinder and a press roller. This is designed in such a way that from the film supply roll, a film strip or a transfer film is passed through the nip between the impression cylinder and press roll.
  • each sheet When transporting the sheets through the printing unit, each sheet is provided with an adhesive pattern. Thereafter, 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, mostly metallic layer forms a close connection with the areas provided with adhesive.
  • the transferred layer adheres only in the area provided with the adhesive pattern.
  • the carrier film is thus removed only the transfer layer in the region of the adhesive pattern. The used in this way transfer film is wound up again.
  • coating units for example in printing units of printing presses. It is also known as a press roller, for example, to use the blanket cylinder or printing cylinder of a printing unit.
  • barrier properties can be achieved.
  • a printed cardboard coated with a plastic film can then be used as outdoor advertising.
  • types of coatings are often required for the application in frozen packaging as a moisture barrier layer or as a packaging of aggressive fats as a grease barrier layer, which is required for example for the packaging of fatty animal feed.
  • the laminated layer may also fulfill decorative purposes, e.g. As a metallic coating or effect and security coating (e.g., a hologram-coated film).
  • the laminated layer may also be added as a reinforcement of the backing material to increase, for example, the tear strength of a package.
  • the object of the invention is to provide in a laminating or laminating a sheet-fed rotary printing press separation possibilities for the effective separation of the film web into sections, so that a residue-free processing of the laminating / laminating is possible.
  • the film web is separated into the individual sections by a separating device whose section length is determined by the laminating or laminating surface of the printed sheet. After separation, the free end of the film web is held firmly by a fixing device.
  • the separation can take place in which the film web is provided by a perforating with perforations or openings of any shape. After passing through the perforation point by the fixing device, the film feed is prevented by the fixing point, while the section connected to the intermediate carrier or the printed sheet is transported further.
  • a printing unit A is provided which is provided with a plate cylinder 3, a blanket cylinder 4 and a counter-pressure cylinder 1. Furthermore, a processing plant B for laminating or lamination of sheet is provided.
  • the finishing plant B consists of a press roll 5 and another cylinder, which form a press nip 12.
  • a laminating or laminating film 7 is applied to the printing sheet.
  • the laminating or laminating film 7 is unwound in an unwinding device from a supply roll 8 as a film web. In the coating process, no film is rewound after the lamination or laminating process.
  • the film web is divided by a separator 11 into film sections which are completely connected to the sheet.
  • the film is applied by the laminating or laminating as a closed film on the sheet by the film unwound from a supply roll 8 and then ironed in the press nip 12 between a press roll 5 and the impression cylinder 1 on the sheet resting on the impression cylinder 1 becomes. After reaching the required section length, the film is torn off or cut off. Characteristic of the invention is that the entire film remains on the substrate and transported on with the sheet and no carrier film, such as for example, in the cold foil transfer process, is wound up again.
  • the sheet transferred to the printing sheet can cover the printed sheet entirely or only in partial areas of the sheet format.
  • a partial lamination / lamination of a printed sheet the recess of the gripper edge at the beginning of the sheet should be mentioned.
  • the transfer of the laminating or laminating film 7 takes place in the press nip 12 between the press roll 5 and impression cylinder 1.
  • the transfer of the film web or of the film web section can be effected directly onto the printed sheet or partially or completely via an intermediate carrier, e.g. a roller against which the film web is applied.
  • the film web 7 is thereby separated into the individual sections by a separating device 11, the section length is determined by the laminating or laminating the sheet.
  • the section length definition may be determined from precursor data or defined, for example, by user input at the machine control station or other operator device.
  • the fixing device 10 may be a suction roll or suction roll group, a roll or a roll group or a pneumatic suction strip. roll have the advantage that they can also be driven and thus can support the advance of the film web during the film feed. They are then stopped when the film web end has to be held at a separation of the film web.
  • the negative pressure can be applied continuously or in phases. For example, during the feed phase, if necessary, the applied negative pressure can be reduced or switched off.
  • the separation can take place, for example, in that the film web is provided with perforations or openings of any shape by a perforating device 16. After passing through the perforation point by the fixing device 10 of the film feed is prevented by the fixing point, while the associated with the intermediate carrier or the sheet section is further transported. This leads to a rupture of the film web at the perforation point 15. A similar effect can be achieved by the introduction of lateral notches 17 in the film web 7. The notches will rupture the films when the film web located behind the score is held by the fixture 10.
  • the introduction of the perforations can be done by means of non-contact perforating means, such as pulsed or pulsed laser devices. Also conceivable are fixed or rotating perforating knives, which cause a mechanical perforation.
  • the film 7 is completely severed after passing through the fixing device 10. This can be done by means of laser or water jet cutting method, but also mechanically in separating cut or paper cut.
  • the separating devices according to the invention can also act against the intermediate carrier or be integrated into the surface of the intermediate carrier.
  • a knife may be integrated into the surface of the press roll 5, so that the film web is severed at each revolution after a fixed section length.
