Abstract
A method is provided for producing a molded part that is deep drawn from a thermoplastic foil. An outer surface of the thermoplastic foil is provided with a positive depth structure, under the effect of heat and pressure, by means of a stamping or embossing roller that has a negative depth structure. In at least one extent of a surface of the embossing roller, the negative depth structure of the roller is compressed in such surface regions thereof that effect a stretching of the foil during deep drawing. Subsequently, at least a portion of the foil is deep drawn.
