Patent number: 6399160Abstract: A method and apparatus for coating a paper or board web, wherein the web to be coated is brought to a film transfer coater and taken to a nip between the film transfer roll of the coater and its backing roll, and coating mix is applied onto the surface of the film transfer roll. The web is taken through the nip between the rolls and the rolls are turned, whereby the coating mix applied onto the applicator roll is at least partly transferred onto the surface of the web. The web is supported through the nip by means of a belt traveling at the same speed as the web, the belt having been arranged to travel on the backing roll. The web is taken onto the surface of the belt prior to the nip and separated from the belt after the nip, and it is pressed against the film transfer roll by means of the belt. The length of the path where the web and the film transfer roll are in contact with each other is controlled by varying the position of the web and the belt.Type: GrantFiled: July 6, 1998Date of Patent: June 4, 2002Assignee: Valmet CorporationInventors: Johan Grön, Jorma Kinnunen, Mikko Tani, Erja Nikula

Patent number: 6177137Abstract: Method and arrangement for coating a web in a film press nip defined by a pair of rotating rolls and through which the web runs and in which a coating agent is applied as a film onto a face of at least one of the rolls and transferred in the nip from the face of the roll(s) onto a respective side of the web to thereby coat the respective side of the web. Steam jets are applied to each side of the web that is being coated to prevent formation of coating-agent mist at a web-outlet side of the nip. The steam jets can be directed from a location after the nip to the web-outlet side of the nip and/or substantially to a point of separation of the web from contact with the roll(s).Type: GrantFiled: October 7, 1997Date of Patent: January 23, 2001Assignee: Valmet CorporationInventor: Rauno Rantanen

Patent number: 5779854Abstract: An adhesive application device includes an adhesive chamber for containing adhesive, an adhesive roll which dips partially into the adhesive, and an adhesive application roll or block roll for applying glue onto a workpiece guided past the block roll by a clamping device. In the absence of a workpiece, a turning axis of the block roll is swung away from the clamping device on an eccentric axis which does not coincide with the rotational axis of the adhesive roll. The turning axis of a block cylinder or the turning axis of an adhesive roll is guided so as to be movable in such a manner that the distance of the block roll from the adhesive roll remains constant.Type: GrantFiled: February 4, 1997Date of Patent: July 14, 1998Assignee: Windmoller & HolscherInventor: Hermann Sandmeier

Patent number: 5547509Abstract: A coating installation is provided for a paper mill to apply a coating to at least one surface of a continuous web of paper. To reduce catastrophic damage to the web of paper passing through the coating installation, a continuous support belt is provided for supporting the web entirely through and beyond the location at which the coating is applied to the web. The continuous support belt is formed from a smooth dimensionally stable material exhibiting appropriate stiffness and compressibility for a particular coating application.Type: GrantFiled: January 23, 1995Date of Patent: August 20, 1996Assignee: Champion International CorporationInventors: Thomas M. Neider, Robert J. Rudt

Patent number: 5303670Abstract: The invention concerns a device for metering of a coating agent onto a moving base, such as a paper or board web. The device includes first and second soft-faced applicator rolls defining a coating nip, through which nip a web is passed. The first applicator roll is journalled as fixed on a frame of the device, and the second applicator roll is linked to the frame of the device pivotally by the intermediate of a loading arm or the equivalent. At least one of the applicator rolls is in nip contact with a hard transfer roll, which is further in nip contact with a soft-faced metering roll. A pond of coating agent is located in a metering nip between the metering roll and a transfer roll. As the rolls revolve, the coating agent is transferred through the metering nip onto the face of the transfer roll and from there further through a transfer nip formed by the transfer roll and the applicator roll onto the face of the applicator roll.Type: GrantFiled: October 4, 1991Date of Patent: April 19, 1994Assignee: Valmet Paper Machinery Inc.Inventor: Rauno Rantanen

Patent number: 4296708Abstract: Metal parts are coated with one or more layers of a solvent-based adhesive using a roller coating procedure. The adhesive solution is transferred from a supply reservoir to the metal part by a natural fiber felt covered roll. The freshly coated part is then dried and the coating and drying procedure repeated until a layer of adhesive of desired thickness is built up. The use of a natural fiber felt covered roll permits uniform transfer and application of the adhesive at efficiencies above 90% (ratio of adhesive on the part to total adhesive used).Type: GrantFiled: February 1, 1980Date of Patent: October 27, 1981Assignee: Ken-Koat, Inc.Inventors: Kenneth L.

Patent number: 4159356Abstract: Heat activated, fabric conditioning products are made by impregnating a thick, absorbent substrate with fabric-conditioner chemicals. Such products are designed for use at elevated temperatures encountered in laundry dryers. This invention provides a process for impregnating the substrate with liquid fabric conditioning chemicals. By limiting the volume of impregnate in contact with the substrate during compression of the substrate in a nip, precise control is obtained over both the quantity of impregnate and the uniformity of the impregnate in the substrate. It is critical that the volume of impregnate available at the nip be limited to a volume equal to or less than the apparent void volume of the substrate when compressed to a thickness equal to the nip gap.Type: GrantFiled: April 7, 1977Date of Patent: June 26, 1979Assignee: Scott Paper CompanyInventor: Richard J. Jablonski
