Definitions

  • the present invention relates to dies for foil stamping machine and more particularly photopolymer dies.
  • Background of the Invention The present invention relates to dies for foil stamping machines, as discussed in USA Patent 5904096 and International Patent Applications PCT/AU00/00428, PCT/AU02/00496, PCT/AU02/00497 and PCT/AU03/00012.
  • Photopolymer dies are generally used at temperatures in the range of 130°C and 165°C. However, there is demand for these dies to be used at temperatures in excess of the above temperatures and including temperatures above 200°C. However, these previously known dies are prone to failure at higher temperatures as they delaminate. It is believed delamination results from gas build up between the photopolymer and the steel backing plate.
  • Object of the Invention It is the object of the present invention to overcome or substantially ameliorate at the above disadvantage.
  • a photopolymer die including: a backing plate having a thickness extending between a first major surface and a second major surface, the plate being perforated so as to have a plurality of passages extending through the plate between the first and second surfaces; a photopolymer layer covering at least portion of said first surface so as to cover at least some of said passages; and an adhesive between the photopolymer layer and said first surface to secure said photopolymer layer thereto.
  • said plate is steel.
  • said thickness is in the range of 0.2mm to 3.0mm.
  • the adhesive is a phenolic base adhesive or an acrylic polymer adhesive.
  • said plate is planar.
  • the plate is arcuate in configuration.
  • the die 10 for a foil stamping machine.
  • the die 10 includes a steel backing plate 11 having a thickness 12 separating a first major surface 13 and a second major surface 14.
  • the 11 is formed with a plurality of passages 15 that extend through the plate 11 between the surfaces 13 and 14.
  • the passages 15 may be punched or drilled.
  • Attached to the surface 13 is a photopolymer layer 16. More particularly the layer 16 is secured to the surface 13 by means of an adhesive layer 17.
  • the photopolymer die 10 is used, particularly at high temperatures at or above 200°C, the die 10 produces a gas 18.
  • the gas 18 can escape through the exposed surface 19 as well as via the passages 15. Accordingly, a build up of gas between the layer 16 and surface 13 is inhibited.
  • the above described preferred embodiment has a number of advantages including being able to operate at higher temperatures without detracting from the life and durability of the die 10.
  • the above die 10 lends itself to a wider range of applications including machines in which the die 10 would be of a cylindrical configuration.
  • the above die 10 particularly has the advantage of allowing gas to escape through the passages 15 while enhancing the fixing of the layer 11 to the plate 12 as the adhesive layer 17 and photopolymer layer 16 penetrate the passages 15 to "key" the layer 16 to the plate 11.
  • the adhesive layer 17 may be in liquid or jelly form when applied and may be applied by any suitable means such as spraying or rolling.
