Publication number: 20100200520Abstract: A fiber suspension is dewatered by being introduced from above into a container formed of a wider endless flexible wire band and a more slender endless flexible wire band, which mutually are lap joined at adjacent border parts, which carry a respective part of a coupling, the wider band being reshaped to a C-shape, by folding its border parts over one of the main surfaces, and bringing them into overlapping contact with the overlapping border parts of the extended more slender band. The screening pipe is established along a common longitudinal section of the tracks of the two wire bands, the lower end part of the screening container being kept substantially sealed, and the fiber suspension being introduced by elevated pressure to a centrally placed nozzle assembly with spray nozzles spaced-apart around the nozzle assembly, toward the screening pipe's inside.Type: ApplicationFiled: September 12, 2008Publication date: August 12, 2010Applicant: METSO PAPER, INC.Inventor: Ebbe Hoden

Patent number: 7757990Abstract: In a reel change in the reeling process of a fiber material web, the fiber material web (W) running to a reel that is becoming full is changed to run around a new reeling core (2) brought to a reel change position in such a way that the web is made to adhere onto the surface of the new reeling core (2). The web (W) is made to adhere onto the surface of the reeling core (2) by a change in the properties of the material on the surface of the reeling core (2). The material is a combination of an adhesive area (6a) on the surface of the reeling core and a protective layer (6b) on top of the adhesive area, and the properties of the material are changed by removing the protective layer (6b).Type: GrantFiled: February 3, 2006Date of Patent: July 20, 2010Assignee: Metso Paper, Inc.Inventors: Jari Tiitta, Pekka Ruha, Topi Tynkkynen, Tatu Pitkänen, Petteri Lannes, Teppo Kojo, Hannu Kasula, Matti Kemppainen

Patent number: 7736695Abstract: A novel method of forming oil in water process is disclosed. According to the invention process are obtained by steps comprising dispersing an oil soluble amine modified polyfunctional polyvinyl monomer and an oil soluble bi- or polyfunctional vinyl monomer along with a thermal or UV free radical initiator (optionally included in one or both of the oil or water phases) and an organic acid into an internal phase oil; heating or UV exposing for a time (and temperature) sufficient to oligomerize the amine modified polyfunctional polyvinyl monomer and oil soluble bi- or polyfunctional vinyl monomer forming a pre-polymer. Thereafter the process involves adding to the oil phase oil a water phase comprising a dispersion in water of an anionic emulsifier (and optionally initiator), and adding an emulsifying agent. Emulsification of the oil phase into the water phase (O/W) is controlled through the quantity of water employed.Type: GrantFiled: May 18, 2006Date of Patent: June 15, 2010Assignee: Appleton Papers Inc.Inventors: Todd Arlin Schwantes, Peggy Dorothy Sands
