  • Patent number: 5284087
    Abstract: A method and marking device for imprinting indicia on the surface of an article, in which a holding strip is adhesively secured onto the surface of the article by an adhesive coating on the strip, the strip supporting, on its opposite surface, marking elements which are separate and distinct from the strip. The marking elements have a thickness substantially greater than the thickness of the strip and project from the strip so that under application of external pressure to the marking elements, the marking elements will be pressed into the surface of the article to leave an imprint of the marking elements therein. The strip with its marking elements is adhesively affixed to the article in the course of a production step in the manufacture and treatment of the article thereby avoiding the need for separate application of pressure to the marking elements.
