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 to use as a press roll, for example, 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 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.
  • Embossing in printing presses is well known from various patents.
  • DD 474 365 an embossing process is described in which is embossed between the form and impression cylinder.
  • the die is mounted on the forme cylinder.
  • the male is attached to the opposite pressure cylinder.
  • the patent publication DE 10 2004 058 601 A1 represents an embossing process that converts sheet or web-shaped substrates between two rotating rolls.
  • the two rotating rollers are provided with tool parts.
  • the patroller acts on the corresponding die roller and thus characterizes the stamped product passed through.
  • Embossing applications in printing presses are in addition to the cited documents known in other forms.
  • the object of the invention is to achieve different optical effects, a haptic detectable film surface and a good bondability of a package.
  • the film is applied by the laminating or laminating as a closed film on the sheet by the film unwound from a supply roll and in a press nip on the sheet, which rests on the impression cylinder, ironed. After reaching the required section length, the film is torn off or cut off.
  • a matt effect is achieved in the surface of the laminating or laminating film by a shiny laminated on the sheet / laminated film in their surface topography by an embossing process partially or flatly changed so that it appears dull.
  • the embossing plate or embossing roll has a fine structure, which is then embossed into the composite of printed product and laminated / laminated film.
  • FIGS. 1 and 2 is in a sheet-fed rotary printing press, preferably sheetfed offset printing press, a printing unit A is provided, which with a plate cylinder 3, a blanket cylinder 4 and a counter-pressure cylinder 1 is provided. 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 mechanical surface treatment of the laminated / laminated film surface and possibly also of the composite Laminated / laminated layer takes place with the sheet.
  • Laminated / laminated films generally have a uniform gloss. Films can have all degrees of gloss between a matt appearance and a high-gloss appearance. In most cases, however, slides will be shiny. In the printing industry, it is often desirable to achieve a matte / glossy effect that, in contrast, gives the printed product a more vivid appearance and a high desired attention value.
  • a matt effect is achieved by a glossy laminated on the sheet / laminated film in their surface topography by an embossing process partially or flatly changed so that it appears dull.
  • the embossing plate or embossing roll has a fine structure, which is then embossed into the composite of printed product and laminated / laminated film.
  • the embossing depth will usually be rather low, so that only the laminated / laminated film is embossed.
  • the reverse process is also conceivable by a matte film is smoothed by an embossing process partially or surface. However, this method approach is useful in most cases, since films are usually equipped with a glossy surface.
  • embossing can serve advertising purposes, for example by embossing a logo. This is then visually and haptically better to capture and gives a high quality of the printed product.
  • the embossing can however also have a functional character, for example in the form of an audaceable braille Braille or in a hard to adjust security stamping.
  • a distinction is made between the high, the low and the high-level embossing.
  • the embossing is embossing of substrates, where an increase on the front of the material is created by the introduction of a recess in the back of the material.
  • the stamping is a stamping form in which the stamping error! Bookmark not defined.
  • Stamping of substrates is produced by a depression on the front of the material.
  • the high / low embossing represents a combination of both Pägeformen.
  • a stamping die with embossing dies patrix for example, against a cylinder, which is optionally protected with a protective film or an apron against mechanical damage, acts.
  • a mold with embossing stamps male and female work together with a corresponding counter-mold, which has corresponding recesses die.
  • the die can be clamped as a mold or formed by molding into a deformable material in the embossing.
  • the mechanical processing according to the invention of the film laminated / laminated onto the printed product can also be a perforation which, for example, is partially introduced into the printed product.
  • Films can not be very well bonded with many commercial adhesives and the adhesion of the adhesive film is often insufficient. Perforation of the closed or laminated film of film can improve the adhesion of adhesives / primers. So it makes sense to perforate adhesive flaps of packaging locally.
  • thermoplastic laminating or laminating film 7. It may prove expedient to temper the embossing roll 6, 13 when using a thermoplastic laminating or laminating film 7. As a result, not only the purely mechanical deformation but also thermoplastic deformation can be achieved.
  • the tempering of the embossing roller 6 and / or 13 can take place in which the pressure roller flows through a tempering fluid or gas becomes.
  • the tempering can also be done by an electric heater, or indirectly by induction or irradiation with a heat radiator.
  • the embossing roller 13 may be formed as a cylinder on which a stamping plate is clamped. In the case of the combined embossing / embossing carry in the embossing D both corresponding cylinder an embossing plate, wherein it is irrelevant in the context of the invention, which cylinder carries the die or male.
  • the embossing roll 6, 13 may also be a solid roll having a surface structure.
  • the structure embossing is generally distinguished from the pictorial embossing.
  • the structure embossing has a uniform or irregular pattern, which is partially or flatly introduced into the substrate.
  • a structure embossing can be a repetitive motif or a defined surface structure.
  • the pictorial embossing is a motif that is usually brought into line with areas of the printed image, for example, an embossed printed logo.
