Definitions

  • the invention relates to a device for hot foil stamping according to the preamble of claim 1.
  • Mirror-smooth surface elements in gold, silver, copper, aluminum and other metallic colors can be transferred to the substrate in hot foil stamping.
  • a carrier film is coated with the coloring layer and a hot-melt adhesive (adhesive layer). Under pressure and heat, the image can be transferred with a heated cliché (high-pressure mold).
  • Suitable machines are either rotary processing stations in printing machines or flat bed punching and embossing machines.
  • Hot foil stamping is primarily used in a wide range of sheetfed and roll products, such as packaging for cosmetics, confectionery and beverages, as well as for high quality brochures.
  • Adhesion forces prevail in the embossing gap between embossing cylinder and counter embossing cylinder when the film is released from the printing substrate. Contrary to these adhesion forces, the foil must be loosened after embossing. The difficulty is that the embossing motif retains a sharp edge and does not "fray", ie that it has a high edge sharpness.
  • Object of the present invention is to provide a device for hot foil stamping, which allows optimization of the embossing quality.
  • the device according to the invention is used for hot foil stamping on sheet-shaped or web-shaped substrates with a heated embossing cylinder, a cooperating with this impression cylinder and a device for providing embossing film.
  • the embossing foil is thereby guided by the device for providing tangential to the embossing cylinder and tangentially to the counter embossing cylinder between these two, that is, without wrapping with only or partial wrap in an angular range of the embossing cylinder or the counter-embossing cylinder.
  • the means for providing embossing foil downstream and spaced from the embossing cylinder and the countermolding cylinder at least one adjustable guide element, for. B.
  • the guide element could thus also be referred to as deflecting element. It can be z. B. either a continuous guide roller or more juxtaposed on a rotary axis guide rollers are used.
  • the guide element is arranged on the side of the device for providing embossing film relative to the transport plane of the substrates. Preferably, both are arranged above the transport plane of the substrates. To adjust the guide element, an adjustment is provided. As a result, the dwell time of the stamping foils on the printing material can be advantageously adjusted and thus the stamping quality can be optimized.
  • the adjustment of the position of the guide element causes a change in the take-off angle ⁇ between the substrate and the embossing film.
  • the guide element is designed to pivot about an axis of rotation for carrying out the adjustment movement.
  • the guide element along be designed to be displaceable in a linear axis, for example horizontally, vertically or transversely, in each case for carrying out the adjusting movement.
  • the device for providing embossing foil has an actuator, in particular an electric motor, for example a servomotor, for carrying out the adjusting movement.
  • the adjustment can be done manually by a machine operator.
  • the actuator can be controlled by a control unit and is controlled by it, for example, depending on a processing speed.
  • job-dependent setting data that is to say setting data relating to the position of the guide element, can be stored in a memory of the control unit, so that the setting data can be recalled quickly in the case of a repeat job.
  • speed-dependent adjustment data of the guide element can be stored in a memory of the control unit and retrievable.
  • a device for hot foil stamping 100 a so-called hot foil stampers, is shown.
  • the embossing foil 1001 is transported through the embossing gap between the cylinders 1, 2 through the embossing cylinder 1 and an embossing cylinder 1 cooperating therewith.
  • the printing substrate 1000 is also transported through the embossing gap between the cylinders 1, 2 in the transporting direction T therethrough. At least on the material-expiring side of the embossing gap of the substrate 1000 is guided tangentially to embossing cylinder 1 and 2 impression cylinder.
  • the embossing cylinder 1 can wear an embossing cliché (not shown) and have a heater for heating this embossing cliché (not shown).
  • the device 3 for providing embossing foil 1001 has an adjusting unit 10 for carrying out an adjusting movement v, v ', v "of the guide rollers 4 or of the guide roller 4.
  • FIG. 1a, 1b and 1c gives the device 3 for providing embossing foils 1001 different deduction angle ⁇ , wherein the deduction angle ⁇ between the guide rollers 4 and guide roller 4 along ongoing embossing film 1001 and the transport plane of the printing material 1000 is.
  • the change in the take-off angle ⁇ is achieved in that guide rollers 4 and a guide roller 4 of the device 3 for providing embossing foil, which guides the embossing foil 1001, by means of a rotating shaft 6 about a rotation axis 5 with a lever 7 designed as a pivot lever is designed to be pivotable.
  • the pivoting adjustment v changes the position of the contact point of the guide rollers 4 and the guide roller 4 with the stamping foil 1001, thus changing the deduction angle ⁇ and the contact area k of substrate 1000 and stamping 1001.
  • the embossing quality can be influenced and optimized.
  • the means 3 for providing embossing foil 1001 of the hot foil stamping machine 100 can have an electric motor 8, which serves for the adjusting movement v of the guide rollers 4 or the guide roller 4.
  • the electric motor 8 is controlled by a control unit 9, in which also setting data can be stored.
  • FIG. 2 is also the device 11 for transporting the printing material 1000 indicated.
  • FIG. 4 Alternative embodiments of the guide element 4 are shown.
