  • Patent number: 6551434
    Abstract: A method of producing an extrusion-laminated member comprises extruding a thermoplastic resin from a T-die into the form of a film and laminating the film on a heated metallic base member using a pair of laminating rolls, wherein a pre-roll is disposed between the T-die and one of the laminating rolls to receive the film on the side opposite to the side that adheres onto the base member over the whole width of the film. The film is wound on the pre-roll at an angle (&agr;) of from 10 to 90 degrees. The film received by the pre-roll is fed to the laminating rolls, conveyed by being supported by the laminating rolls on the side opposite to the side that adheres onto the base member, and is fed to a nipping position so as to be melt-adhered onto the heated metallic base member.

  • Patent number: 6548428
    Abstract: The invention consists of a multilayer material and a process for manufacturing this material. The multilayer material comprises a polyester substrate which is provided with a thermoset plastic polymer coating and a layer of contact adhesive. The polymer coating is produced by a reaction between a polyurethane polymer containing hydroxyl groups and a low molecular linear polyisocyanate, with catalytic tin-organic additives and colorants. The multilayer material is resistant to tearing and is also weather-resistant. A transparent, reactive layer, consisting, for example of a layer to take toner or ink, or a metallic layer, can be deposited on the side opposite to the polymer-coated substrate. Multilayer materials of this kind are suitable for large-scale covering of supporting frameworks in the construction of model aircraft and are also suitable as a medium onto which images and print may be applied using a plain paper copier, and can also be used to carry advertising.

  • Patent number: 6547912
    Abstract: A process for making a protective and decorative surfacing film comprises extrusion coating a solventless polymeric material from an extruder die to form an optically clear first layer on a polyester carrier sheet traveling past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followed by applying a pigmented second layer to the first layer. The composite paint coat is transferred to a reinforcing backing sheet, after which the carrier sheet is separated from the paint coat to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the pigmented second layer. The pigmented second layer can be solvent cast and dried or extruded and hardened as a separate coating on the first layer. The composite paint coat can be bonded to a coextruded size coat and semi-rigid plastic substrate panel to form a thermoformable laminate.

  • Patent number: 6217695
    Abstract: A method and apparatus for applying an extrudable material to a substrate, in which a concentrated light beam is directed onto the substrate before or after the application of the extrudable material. The energy of the beam is concentrated on the substrate surface, wherein it is subsequently transferred to the extrudable material deposited on its surface, thereby increasing the temperature and lowering the viscosity of the closely situated material so as to facilitate material penetration into the substrate. This method allows the use of illumination of modest energy density, of wavelengths absorbed by the extrudable material, or of such cross-sectional extent that it may not be transmitted through the extrusion device by which the extrudable material is deposited.
