    • The present invention relates to a method for the production of shapings on the circumference of the die, by synchronizing the operations of cold hobbing, and CNC milling and turning. This method involves the construction, at the outside of the effigy of the working punch, of reference systems (in negative) and a groove (in negative) along a generatrix thereof. The working punch slides in a retaining sleeve provided with a tooth (positive) such as to perfectly matching with said groove. Both the working punch and the retaining sleeve, once keyed to one another are positioned along a reference axis of the press and in the upper position to the tip to be punched.
      Once the hobbing occurred, the resulting "barrel tip" of the die presents on the effigy the reference systems (positive) in the neighborhood of the effigy. On the spindle of the CNC lathe, a coupling element provided with reference counter-reliefs (in negative) is keyed in axis with the lathe itself. Therefore, the operator of the CNC lathe ensures the flatness of the "barrel tip" by engaging the reference systems while the axiality is ensured at the closure of the terminals of the spindle, and this allows the working in registry of the die.

    • The invention relates to an embossing film, in addition to an associated carrier film for applying surface structures, in particular to fibreboard. The invention also relates to a press and to a production method that uses the embossing film. The advantages of the inventive embossing film are that its use during the pressing process is low-maintenance and obtains a particularly even surface structure. In an additional embodiment, the embossing film has one or more metallic additives, in particular aluminium additives. This improves the strength of the film, in particular during the pressing process and improves the thermal conductivity of the embossing film. The heat that occurs or is produced during the pressing process for curing the resins that are used can thus be dissipated more efficiently from the panel. In a further embodiment, the embossing film comprises an acrylate, which increases the mechanical stability of said film. The acrylate can be applied in the form of a dispersion to the carrier film or paper and is pressed into the film or paper in a roller pressing process. The high mechanical stability permits the film to undergo the embossing operation several times, thus reducing production costs. In addition, the thickness of the film can be reduced, without any detrimental effect on the required stability. Said reduction also increases the thermal conductivity of the film, again reducing production costs.
