Abstract
A method for obtaining a cellular foam product having its surface configured, which comprises incorporating an expanding agent into a foamable resinous composition and subsequently heating the composition to a temperature to decompose the blowing agent and form a cellular layer, characterized by producing said cell layer with portions of the surface of said layer at a level that contrasts with the level of the surface of the remaining portions of said layer by applying to said portions of the surface, before said heating, an inhibitor, which substantially alters the temperature at which the blowing agent decomposes in said portion, and controlling the degree of said heating to produce said thickness contrast.
