Abstract
Abstract A method of providing foam plastic surfaces with a relief structure comprising the steps of: producing printed films which contain at predetermined locations, substantially corresponding to the printing pattern, either (a) means which inhibit and/or accelerate foaming, or (b) a barrier layer material which prevents the throughpassage of the means which inhibits or accelerates foaming, applying the film, prior to foaming, to the base layer to be foamed, and this combined or composite material is heated to the foaming temperature, whereby by means of the migration of the means inhibiting and/or accelerating foaming in accordance with the printing pattern of the film into the base layer during foaming there is obtained the relief formation of the surface and the anchoring of the printed film at the surface. There is also provided means for providing foam plastic surfaces with a relief structural design, which is characterized by the features that said means comprises an imprinted non-foamable self-supporting film or an imprinted film located at a carrier material, and wherein predetermined locations of the film corresponding to the printing design contain either, (a) means which inhibit and/or accelerate foaming, or (b) a barrier layer material which prevents the passage of the means inhibiting and/or accelerating foaming.
