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 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.
  • 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 as an effect and safety coating, e.g. a foil provided with holograms.
  • 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 improve the adhesion of the laminated or laminated layer on the printed product in a sheet-fed rotary printing press.
  • the film is applied by the laminating or laminating device as a closed film on the printing sheet.
  • the film is unwound from a supply roll and ironed in a press nip between a press roll and the impression cylinder as a whole on the sheet, which rests on the impression cylinder. After reaching the required section length, the film is torn off or cut off.
  • the entire film remains on the substrate and transported on with the sheet. There is therefore no remainder of a carrier film, as for example in the cold foil transfer process, which would have to be wound up again.
  • 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 further transported with the sheet and no carrier film, such as 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 takes place in the press nip 12 between the press roll 5 and impression cylinder 1.
  • the laminated or laminated film is rolled over after the press nip by a further roll to improve the adhesion.
  • the additional press roller 6 to improve the adhesion of the laminated or laminated film may be directly downstream of the press nip 12 and act against the same impression cylinder 1 as the press roller 5.
  • the additional roll for improving the adhesion of the laminated or laminated film may also be a separate calendering unit D in which a press roll 13 acts against the film laminated or laminated on the printing sheet.
  • the downstream of the laminating unit B in the sheet transport direction roller 13 to improve the adhesion of the laminated or laminated film on the sheet and part of the calendering D is a form cylinder or blanket cylinder of a varnish or printing unit.
  • the additional press roll 6 or the downstream roll 13 for improving the adhesion of the film transferred to the printing sheet in the laminating / lamination unit or both rolls 6, 13 can be tempered, thereby improving the adhesion of thermoplastic films.
  • the tempering of the additional pressure roller 6 or the downstream roller 13 can take place in which the pressure rollers 6, 13 are flowed through by a tempering fluid or gas.
  • the temperature control but can also be done by an electric heater, or indirectly by induction or irradiation with a heat radiator.
  • the adhesion of the laminated or laminated film is significantly improved on the sheet and even small disturbing unevenness of the surface topography equalized, this I interfere with the visual appearance of the printed product.
