  • 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 relative to the press cylinder 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 cylinder 3 and the impression cylinder.
  • the pressing cylinder 3 may be a blanket cylinder of an offset printing unit.
  • the pressing cylinder 3 may also be the forme cylinder of a paint module. It is essential that the surface of the pressing cylinder 3 so the blanket cylinder or forme cylinder is equipped by means of a compressible, damping element.
  • the pressing cylinder 3 can be pressed with a press, for example as a plastic coating, comparable to a blanket or blanket, be provided.
  • 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 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 contoured pressing surface can be provided as the surface of the pressing cylinder 3.
  • a pressing surface limited to the area to be coated is used on the pressing cylinder 3.
  • a cut-out printing blanket, an imageable plastic printing form or a pressure pad which can preferably be releasably fastened to a smooth base, possibly stickable or magnetically attachable, can be used to support the limited pressing surface.
  • 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.
  • the utilization of the transfer film 5 can be improved even in zonally different lengths coating areas within an arc.
  • the image-forming layer for example a metallization layer, can be produced by means of an adhesive which reacts to ultraviolet radiation be applied.
  • so-called UV negative pressure paint can be applied. This UV negative pressure ink is applied by means of the applicator 1 for the adhesive in a corresponding manner via an offset printing plate.
  • a device for UV drying must be arranged.
  • the adhesive effect of the UV negative pressure ink is slightly better than that of a normal adhesive. This results in improved smoothness and thus gloss effect of resting on the sheet imaging layer.
  • a UV dryer 15 is to be provided either after the applicator 1 for predrying the adhesive application.
  • a UV dryer 15 penetrating the imaging layer can be arranged, for example, on the impression cylinder 4 of the coating unit 2.
  • the adhesive effect of the UV negative pressure ink can be fully utilized and the smoothness of the coating is increased.
  • the adhesive media required in the transfer of the imaging or metallized layer can, as described, be of different consistency and require different processing criteria
  • the adhesive is applied by means of an arrangement of an anilox roller and a chambered doctor blade over the blanket cylinder or blanket cylinder 3.
  • a high-pressure mold is arranged on the blanket cylinder 3, which carries the Klebersujet.
