Patent number: 4420510Abstract: A method of uniformly applying a foamed adhesive to a normally moving substrate which is subject to stops and starts at irregular intervals. A uniform spread weight of adhesive is applied during a deceleration period and startups can be accomplished without causing puddles or gaps. The method is especially useful in conjunction with an automated plywood lay-up line. Foamed adhesive is supplied under pressure to an extrusion head. When a line stoppage is sensed a first valve above the extrusion head closes. Adhesive within the head continues to expand and fall onto the substrate, but does so at a descreasing rate during the deceleration time. As the substrate comes to a complete stop a second valve prevents further adhesive from being applied. Before a startup, the adhesive in the system is reconditioned by passing it into a recycle line until foam quality andpressure drop across the extrusion head have again assumed normal operating parameters. Only then is the substrate movement started.Type: GrantFiled: March 23, 1982Date of Patent: December 13, 1983Assignee: Weyerhaeuser CompanyInventors: Arden L. Kunkel, Darrell E. Pierson

Patent number: 4391853Abstract: The disclosed adhesive products include a carrier sheet bearing a polymeric film and an adhesive layer, overlying the film as in dry transfers or underlying the film in products such as wire markers and other labels, or there may be adhesive layers both over and underneath the polymeric film. A constituent initially contained in the polymeric film layer migrates into an ordinarily non-tacky precursor of the adhesive layer, thereby rendering the precursor tacky. The precursor layer becomes adhesive only where it is opposite the polymeric film, being non-tacky outside the area of the film. In important applications, the common area of film and adhesive layers does not cover the whole carrier sheet. Both the adhesive precursor layer and the polymeric film may include portions extending outside the common area.Type: GrantFiled: December 10, 1979Date of Patent: July 5, 1983Assignee: The Datak CorporationInventor: David W.

In a specific example, a hollow elastomeric finger is nested within the thimble after dispensing a measured quantity of conductive ink into the thimble bottom. A gas jet applied to the ink from the finger lower end flows the conductive ink throughout a coating cavity below a shoulder in the finger after the ink quantity is substantially all applied to cavity walls, it no longer blocks a cavity vent, and allows the gas to flow freely through the cavity. Gas flow is then discontinued, and the finger withdrawn from the thimble.Type: GrantFiled: October 1, 1979Date of Patent: April 28, 1981Assignee: General Motors CorporationInventor: John Trevorrow

Patent number: 4263348Abstract: For striping pencils, paint is extruded through die orifices in the walls of a passage through which the pencil is advanced longitudinally. The orifices are formed in lands which engage corresponding side regions of the pencil and guide the pencil through the passage. The passage is formed in a block having parts that are supported for relative movement along guide rods and are urged together resiliently. Each block part may have at least one paint reservoir with a duct extending from the reservoir and terminating in a die orifice. The paint, which is supplied to the reservoirs under pressure from a separate source moves longitudinally of the pencil in shallow channels as it issues from the orifices and spreads laterally to an extent depending upon viscosity of the paint, forming stripes of width greater than that of the orifices.Type: GrantFiled: July 30, 1979Date of Patent: April 21, 1981Assignee: Hasbro Industries, Inc.Inventor: Charles G.

Patent number: 4262036Abstract: A pair of horizontally disposed nozzles above a horizontally disposed seal edge surface for coating a frit slurry in a closed pattern on the surface are moved in opposite directions from an abutting, mutually blocking position until the nozzles again come into sealing abutment at a second point above the surface. During the travel of the nozzles, a frit slurry is discharged therefrom at a constant rate and is deposited in a uniform stripe on the seal edge surface. Just before the nozzles abut at the end of the coating operation, the flow of frit slurry from one of them is terminated. This permits the frit slurry from the second nozzle to make a tapered overlay of the frit slurry from the earlier cut off nozzle without forming a bump or extra width at the joint. A rectangular gear generally conforming to the shape of the seal edge surface to be coated is employed to drive the nozzles at a substantially linear speed along the seal edge surface.Type: GrantFiled: March 27, 1979Date of Patent: April 14, 1981Assignee: Sony CorporationInventors: Hideki Mineyama, Shinzo Takei

Patent number: 4256526Abstract: Hot melt adhesive is applied to a moving substrate in a pattern including at least two lines which extend transversely to one another, by conveying the substrate past a nozzle orifice through which a first line of molten adhesive is applied, as by extrusion, to the substrate parallel to the direction of substrate movement and, while continuing to move the substrate in the same direction, projecting another portion of the molten hot melt adhesive onto the substrate as a burst in the form of a flat sheet issuing from a fan spray orifice, this orifice being oriented so that the sheet is projected transversely to the direction of substrate movement, and terminating the burst so rapidly that the adhesive so projected is deposited on the moving substrate in the form of a line having a length in the crosswise direction that is several times its width.Type: GrantFiled: January 25, 1979Date of Patent: March 17, 1981Assignee: Nordson CorporationInventor: David C.

Patent number: 4230742Abstract: A means and method are provided for applying material to a substrate. In the means and the method, material is dispensed onto belt means and the belt means brought in contact with the substrate so as to transfer at least some of the material onto the substrate. The invention is particularly adaptable to the application of a band of silicone type material to a riser of an anode to be used in an electrolytic film-forming metal capacitor, the band of silicone type material helping to protect the anode riser during capacitor manufacture.Type: GrantFiled: December 12, 1977Date of Patent: October 28, 1980Assignee: Emhart Industries, Inc.Inventor: Gerhart P.
