ABSTRACT:
In accordance with a preferred embodiment of this invention, a linear stitching design having improved definition is embossed onto the surface of a hot, thermoplastic sheet. During embossing the sheet is placed over a special anvil formed of an elastomer strip arranged in the pattern of the stitching and inlaid in a rigid support member. The support member confines the elastomeric anvil member such that during the embossing operation the anvil promotes more uniform distribution of pressure on the sheet and forces it into full contact with the embossing die.
