  • Patent number: 5776046
    Abstract: A method of producing doilies includes coating sheets of paper stock with a lubricious release fluid, collecting the sheets into a multi-layered web, and cutting and embossing doilies from the web. The fluid is preferably a solution of mineral oil and silicone, and results in the doilies being more easily separable after being adhered by the cutting and embossing process. A solution of mineral oil and 15%-40% silicone is disclosed.

  • Patent number: 5753335
    Abstract: A doily includes a substrate with multicolor artwork coating substantially covering the top surface. The artwork coating is applied by four color, or more, process printing. A peripheral margin defines patterned cutouts which diminish the substrate and artwork coating, thereby relatively emphasizing the artwork coating in a substantially imperforate central area. The substrate is foil/paper lamination or paper, including precoated paper. The doilies are made by printing rolls of substrate sheet material, layering sheet from plural rolls, and cutting and embossing plural doilies in aligned stacks.
