  • Publication number: 20010042589
    Abstract: A process is disclosed for producing a transfer member to be used in a transfer system by which a toner image formed on a first image-bearing member is transferred to a second image-bearing member. The process comprises the steps of melt-extruding an extrusion material from a circular die of an extrusion/forming apparatus into a cylindrical film; and measuring the circumference of the cylindrical film and sending the resultant information to the extrusion/forming apparatus to adjust the circumference of the cylindrical film. Also disclosed are a transfer member produced by such a process, and an image-forming apparatus having the transfer member. The transfer member can be produced as an intermediate transfer belt or a transfer belt which have a stable peripheral length.

  • Publication number: 20010008165
    Abstract: Disclosed is a finger tape for aiding bowling. The thumb, the middle finger and the ring finger are inserted into holes formed in a bowling ball. Upon bowling, a player grips the ball by inserting the thumb, the middle finger and the ring finger into the holes formed in the ball. For releasing and rolling the ball, the thumb is instantly slipped out of the hole, followed by the middle finger and the ring finger while spinning the ball. Accordingly, an elasticized cotton tape with gravure printed acryl resin adhesive having different effects depending on actions of the fingers is attached to the thumb, the middle finger and the ring finger to obtain effective bowling results, wherein the thumb tape slides easily and the finger tape provides better grip, based on differing amounts of hardener in the adhesive.

  • Patent number: 6159331
    Abstract: A bridging agent for improving the bond between incompatible component layers of laminates comprising one or more N-substituted melamine compounds. The bridging agent is comprised of an N-substituted melamine, an N-substituted melamine formaldehyde resin, a hybrid N-substituted melamine resin, or mixtures of these resins. The bridging agent improves bonding between laminate layers known not to bond well together such as between a styrenated polyester top coat and a melamine impregnating resin. As a result of improving the bond between the incompatible component layers, the bridging agent improves the blister resistance and cove forming characteristics of the laminate. The bridging agent can be used to improve bonding both with and without an overlay paper layer.

  • Patent number: 5490893
    Abstract: A process for making a thermoformable conductive plastic laminate for use in making plastic parts adapted for electrostatic spray painting of a uniform high quality paint finish includes forming a matte release coated casting sheet, casting an electrically conductive polymer in thin film form on the casting sheet, drying to form a conductive primer coat, and transfer-laminating the conductive coating to a thin, thermoformable plastic face sheet. The matte release coat has a fine particulate filler that transfers a micro-roughened matte surface to the conductive primer coat. The conductive primer includes a polyester resin containing a fine particulate conductive material such as carbon black and, preferably, an anti-blocking agent such as fumed silica. The primer coated face sheet can be thermoformed and bonded to a underlying plastic substrate panel.

  • Patent number: 5472541
    Abstract: A method of coating the surface of semi-rigid porous materials such as open cell foam or fibrous compositions with a thermoplastic adhesive in powder form which will reactivate. The powdered adhesive in a size range of 0-600 microns will remain on the surface of such materials even when cell diameter of the foam or space between fibers is larger than adhesive particle size. High porosity is maintained in the coated product. First a thermoplastic adhesive in powder form is dispensed uniformly onto the surface of a carrier belt which is coated with a release agent and is moving continuously. The adhesive advances to a preheating station where the adhesive is plasticized and will adhere to the carrier belt to prevent movement, after which the foam or fibrous material is placed on the adhesive which is adhered to the belt. The adhesive and material advance to a second heating station where the adhesive is fully melted to allow the adhesive to bridge cells in the foam or space between fibers.

  • Patent number: 5470418
    Abstract: A method of producing a succession of self-adhesive labels on a length of release material, which method comprises the steps of:(a) applying a layer of pressure-sensitive adhesive to a surface of a length of release material;(b) applying a succession of individual labels to the layer of pressure-sensitive adhesive so as to adhere the labels to the release material;(c) cutting through each of the labels and the layer of pressure-sensitive adhesive as far as the release material thereby to form the required self-adhesive labels; and(d) removing the waste portions of the applied labels and the waste portions of the pressure-sensitive adhesive which surround the self-adhesive labels from the release material. The present invention also provides apparatus for producing such self-adhesive labels.

  • Patent number: 5429850
    Abstract: An adhesive tape is provided which is obtained starting from a roll of composite material consisting of a first continuous strip or tape of film material and a second continuous strip in a material having low adherence to adhesives, such as a siliconized continuous backing strip, the film material being a high-strength polymeric material film having adhered to one face thereof at least one extremely thin continuous run of adhesive obtained by applying said continuous backing strip onto said tape whereby said adhesive remains on said tape after removal of said continuous backing strip by virtue of the greater adhesion of said adhesive to said tape than to said continuous backing strip, said adhesive tape being useful for splicing continuous webs of thin films.

  • Patent number: 5407697
    Abstract: A method of continuously painting one side of a moving substrate metal strip (1) utilizing a thermosetting polymer based paint composition comprises pre-heating the strip in a pre-heat furnace (2) to a pre-heat temperature above the glass transition temperature of the paint composition, driving a solid block (8) of the paint composition into collision with the strip at a predetermined block speed to cause liquid paint to be melted from the block and applied to the strip at a precisely controlled deposition rate. The deposit, which for thin paint coats is discontinuous, is then spread over the surface of the strip by a pressure roll (14) and emerges therefrom as a smooth coat of wet paint. A bead of liquid paint (17) builds up on the strip on the up stream side of the pressure roll and the block speed may be adjusted in response to the bead size. The emergent strip then travels through a paint curing furnace (5) and a bath (6) to complete the process.

  • Patent number: 5328534
    Abstract: A method of forming a transferable pattern or image of an inorganic film by coating an embossed substrate with an inorganic layer, that may comprise one or more films, over both recessed and raised surface portions, adhesively laminating a transfer substrate to the inorganic layer coating the raised surface portions of the embossed substrate and separating the embossed substrate and the transfer substrate. The adhesive is selected such that the bond between the transfer substrate and the inorganic film on the raised surface portions is greater than the bond between the inorganic layer on the raised surface portions and the embossed substrate.The embossed substrate resulting after removal of the inorganic layer coating the raised surface portions may be modified to include additional inorganic layers over the recessed surface portions by tinning or electroplating methods such that this thickened inorganic layer may also be transferred from the embossed substrate to a transfer substrate as set forth above.
