(DE) VORRICHTUNG UND VERFAHREN ZUM ERWÄRMEN EINES WERKZEUGS
(EN) DEVICE AND METHOD FOR HEATING A TOOL
(FR) DISPOSITIF ET PROCÉDÉ DE CHAUFFAGE D'UN OUTIL
Abstract
(EN)
The disclosure relates to a method and a tool for embossing/pressing a blank with an active surface. The tool has a stack of layers including a coil carrier layer (21) with a coil, and an electrically conductive top layer (25), adjacent to the active tool surface. The top layer is heated during embossing/¬pressing by feeding power to the coil. A cavity (47) is formed between two layers in the stack beneath the top layer (25) as seen from the active surface, the cavity extending beneath a greater part of the active surface and being filled with a fluid, such that applied pressure over the active surface is equalized while the top layer (25) is heated.
