  • Patent number: 6278562
    Abstract: A filter for absorbing electromagnetic radiation which is used in heating a welding zone wherein a first part is joined to a second part. The filter includes a filter housing which contains a chamber within which a fluid is placed. The fluid absorbs undesired wavelengths of radiation from a heating source before the radiation reaches the welding zone. A heat exchanger may be connected to the filter in order to cool the fluid during the filtering process.

    Abstract: The invention relates to a process for applying coating films to three-dimensionally curved substrates, and to a process for producing coating films. In order to apply the coating film, which has at least a coating layer and an adhesive layer, the radiation-curable coating layer of the coating film is partially cured so as to be free from tack before being applied to the substrate. Following application, the coating film is subjected to electromagnetic radiation at below the wavelength of the visible spectrum and is fully cured. To produce a coating film, the coating layer is partially cured so as to be free from tack and in this state is stored until it is applied to a substrate. The coating layer can be attached at least indirectly to a smooth support base in conjunction with an adhesive layer. The coating layer and/or the coating film can be detached from a roller in applying the coating film to a substrate.

  • Patent number: 6221194
    Abstract: Two electroluminescent substrates, each emitting light having different color, are laminated and bonded together with adhesive layer interposed therebetween. An insulation film such as an epoxy film is placed between two substrates and deformed into an adhesive layer under pressure and heat. The adhesive layer serves as a bonding material and a humidity-protection layer as well. Electrical connection between electrodes of the electroluminescent substrates and outside driving circuits is made at the same time two substrates are bonded by the adhesive layer by bonding wiring sheets together. To further improve the humidity-protection ability of the adhesive layer, the surface of the electroluminescent substrates may be covered by resin which is hardened by radiating ultraviolet light at the same time the insulation film is deformed into the adhesive layer. Thus, the electroluminescent display panel having two substrates can be manufactured in a simple and inexpensive manufacturing process.

    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.

  • Patent number: 6171682
    Abstract: Apparatus for continuously producing a web (1) which is corrugated from a thin sheet material which is elastic at least in a transverse direction of the web. The apparatus includes a guide bed (2) which has grooves extending parallel or inclined to each other in the direction of movement of the material. The apparatus also has holding-down devices (5) arranged opposite the grooves of the guide bed (2) so as to urge the web passing between the surface of the guide bed (2) and the holding-down devices (5) into the grooves of the guide bed (2) to obtain corrugations in the web. Finally, at the outlet end (4) of the guide bed (2) is an apparatus or substance which substantially prevents the formed corrugations from springing back to the original condition. A process for producing a strip and an absorbent article containing corrugated strips are included.
