  • Patent number: 4076789
    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, formable plastic sheet and then coated in one operation. The improved definition is achieved by employing a restrained elastomeric anvil to support the sheet during the embossing operation. The elastomeric anvil provides a relatively uniform distribution of pressure on the sheet during the embossing step and urges the sheet into intimate contact with the recessed features on the embossing die surface. Once the sheet is formed but before the embossing die and anvil surface are separated, paint is injected through passages in the embossing die onto the surface of the thermoplastic sheet. The paint is injected under sufficient pressure to force the thermoplastic sheet, which is supported by the elastomeric anvil, away from the die surface; this provides the necessary space to allow the paint to flow onto specified areas of the sheet.
