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.
  • 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 film 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 provide an economically useful device for laminating or laminating printed products in sheet-fed rotary printing press.
  • a film is applied by a laminating or laminating as a closed film on a sheet.
  • the film is unwound from a supply roll and ironed in a press nip between a press roll and an impression cylinder on the sheet, which rests on the impression cylinder.
  • the film is torn off or cut off.
  • FIG. 1 This shows the only one FIG. 1 a device according to the invention in conjunction with a sheetfed offset printing press.
  • a printing unit A is provided which is provided with a plate cylinder 3, a blanket cylinder 4 and an impression 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 which rests 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 film 7 is unwound from a supply roll 8 at a continuous speed V1, which is smaller than the surface speed V2 of the press roller 5, depending on the sheet format and possibly user inputs to the console and other specifications.
  • the speed V1 becomes dependent increased or decreased by the machine speed, but remains in a fixed or approximately fixed ratio to the surface speed V2 of the press roll. 5
  • the film web 7 is temporarily buffered in a buffer in the times in which no film application takes place.
  • the cache can be in known Way are formed by a dancer roller 9 or a dancer roller group 9. If a film application, the cache is emptied, so that sufficient film material for the application process is present.
  • the web tension must also be maintained after the cut or the separation of the film web 7 on the laminating and lamination by the cutting or perforating 11, otherwise the free after the separation end of the film would run back into the buffer with the dancer rollers 9.
  • the fixing device may be two rollers, one or more suction rollers or strips, or any other suitable device which is suitable to fix the free end of the sheet.
  • the film web 7 is released. This can be done, for example, by releasing the rotational movement of pinch rolls or rollers, reducing the negative pressure of suction rolls or strips or releasing the clamping of a clamping device. If there is no film application, the free end of the sheet is clamped and the storage structure of a film store takes place.
