  • Patent number: 5087495
    Abstract: The present invention is directed to a transfer sheet for selectively transferring a transfer layer to xerographic images on a receiving substrate such as paper. The preferred transfer sheet comprises, in successive layers, a carrier film, a metallic film and an adhesive, the adhesive containing a dispersion of 0.5 micron or larger particulate material. In the preferred embodiment, the invention comprising an assembly for use in the process of making a selective transfer to xerographic images on sheet material. The assembly comprises a backing sheet, a transfer sheet and a connector (such as a length of adhesive tape) securing the backing sheet to the transfer sheet at the leading edge of the assembly.

  • Patent number: 4724026
    Abstract: The present invention is directed to a method for selectively transferring metallic foil and xerographic images on a receiving substrate such as paper. The method generally comprises providing a transfer sheet (including a metallic film) and a receiving substrate (including xerographic images disposed thereon.) The receiving substrate is placed in face-to-face contact with the transfer sheet to form a sandwich with the xerographic images on the inside. the sandwich is then fed through an apparatus, where heat and pressure are applied, causing the xerographic images to tackify and causing the metal film from the transfer sheet to selectively adhere to the xerographic images.

  • Patent number: 4110152
    Abstract: An embossing roller has protruding lands extending radially outward from the surface of the roller to provide corresponding indentations in a thermoplastic surface to which the roller may be applied. A layer of resilient material underlies the lands so that when the roller is rolled over an irregular surface, individual lands, or groups of lands, may be depressed different amounts so that embossing indentations are formed in all portions of the surface. By applying adequate pressure to the roller, all of the lands are depressed at their points of contact when in contact with the surface if the surface is flat and regular. The lands are forced by action of the resilient material into contact with the bottom of any slight concavity in the surface and adapt to any slight convexity. In some embodiments, lands protrude outwardly from metal rings which encircle the roller. In other embodiments, lands are supported directly by the resilient material.
