  • Patent number: 5391249
    Abstract: A method and apparatus for producing internally apertured pressure-sensitive labels adhered to a non-apertured liner begins with a label web adhered to a first liner. The internal aperture shapes are cut through the web only and not through the liner, forming aperture slugs separate from the web. The first liner is then removed from the web, and the separate aperture slugs adhere to and are removed with the liner. Next, the web, with apertures cut out, is adhered to a second liner and the label peripheries, in registry with the apertures, are cut through the web only and not through the liner, forming labels separate from the web. Finally, the web is removed from the second liner, leaving individually internally apertured labels on the non-apertured second liner.
