Patent number: 4703715Abstract: A liquid applicator machine of the type operative to apply a liquid such as glue to a moving paper web or the like through a high speed transfer roll which receives a metered film layer of liquid thereon from a pan roller. A static ring is supported in coaxial predetermined spaced relation to each end edge surface of the transfer roll and has an outer annular surface overlapped by the pan roller such that liquid carried upwardly by the end surfaces of the pan roller engages the static ring and is prevented from accumulating at the end edges of the transfer roll and being slung therefrom during high speed rotation of the transfer roll. The invention finds application with full width and segmented transfer rolls to prevent fluid slinging therefrom.Type: GrantFiled: May 28, 1986Date of Patent: November 3, 1987Inventor: Bruce A.

Patent number: 4064288Abstract: An apparatus and method for making continuous, elongated strips or webs, of electrically conductive, flexible material having individual and successive deposits, or patches, spaced apart therealong, each deposit comprising a cathode layer on one face of the strip, oppositely disposed to an anode layer on the other face of the strip, characterized by the layers being in exact peripheral registration with each other.The registration is obtained by reverse roll coating a first such layer on the advancing strip in a first zone so that it extends above the surface of the strip, then training the advancing strip around a roll, in a coating roll nip, with the first layer down and supported on the roll surface and simultaneously reverse roll coating the second such layer on the exposed face of the strip in said nip, while the portions thereof surrounding the raised first layer are flexed out of the plane of the strip, thereby permitting the first layer to control the deposit of the second layer to register therewith.Type: GrantFiled: March 11, 1976Date of Patent: December 20, 1977Assignee: Vertipile, Inc.Inventors: Hemendra K. Shah, William G. Turner

Patent number: 4059069Abstract: Aluminum or other coating material is deposited on the surface of one side of a strip after which ink is deposited on preselected areas of the coated strip. The ink is then cured and the aluminum removed from the uncovered areas after which the ink is removed from the covered area of the aluminum.Type: GrantFiled: August 30, 1976Date of Patent: November 22, 1977Assignee: The Arnold Engineering CompanyInventor: Donald T. Ford

Patent number: 4055688Abstract: A method of, and apparatus for, applying a synthetic resin or plastic powder in a grate-shaped coating to web material wherein an upper layer is formed so as to coincide with and lie upon a lower layer applied by a relief-like structured printing roll. The upper layer is also formed by a relief-like structure printing roll. The powder for both layers, during its transfer into the spaces of the rolls, is brought to its sinter temperature, whereas the web material, before forming the lower layer, is heated approximately to the plasticizing temperature of the powder for this layer. The powder piles of the upper layer are placed upon those of the lower layer directly after transferring the latter to the web material.Type: GrantFiled: May 13, 1976Date of Patent: October 25, 1977Inventor: Hans-Peter Caratsch

Patent number: 4041197Abstract: A method is disclosed for coating a substrate or web with a plastic material. A liquid plastisol coating is applied to the web and the coated web is then passed between a put-on roll and a heat drum, which heats and cures the plastisol. The put-on roll is pressed against the heat drum to compress the coated web. The plastisol is partially cured to gelation while being compressed by the put-on roll, and the curing of the plastisol is completed during further travel of the web around the heat drum.Type: GrantFiled: December 29, 1975Date of Patent: August 9, 1977Inventor: Rudy L. Gagne

Patent number: 3991708Abstract: An adhesive applicator of the gravure-type is provided for continuously applying spots of adhesive onto a travelling web with the use of a roller of the intaglio type. A filling device having a spring loaded shoe element bearing against the roller fills the cavities of the roller with adhesive under pressure from a closed adhesive reservoir. The web is moved by a pin wheel disposed adjacent the roller, and spots of adhesive from the filled cavities are continuously applied to the web as it is intermittently forced to track the applicator roller by means of spaced pads provided on the wheel.Type: GrantFiled: June 23, 1975Date of Patent: November 16, 1976Assignee: Moore Business Forms, Inc.Inventors: John W. Huebschmann, H. Dean Packard, William D. Swiercz

Patent number: 3989569Abstract: A continuous ink-transfer printing system employing a hot-melt wax imaging composition supported on a strong pressure-conforming plastic film web which is continuously recoated with fresh imaging composition to replace imaging composition which is imagewise transferred at a pressure-imaging station. The system comprises an ink-coating station, a pressure-imaging station and an ink-melting station associated with the ink-coating station.Type: GrantFiled: February 10, 1975Date of Patent: November 2, 1976Assignee: Columbia Ribbon and Carbon Manufacturing Co., Inc.Inventor: Douglas A. Newman
