Patent number: 7832677Abstract: A method and an apparatus for controlling the cross-directional nip profile of a reeling nip in a reeler, in which the reeling nip is arranged by means of a reeling core or a growing machine reel and at least one loop of an endless supporting member continuous in the direction of the axis of the reeling core. To control the cross-directional nip profile of the reeling nip, variables proportional to the tension of the supporting member are measured, cross-directional tension profile of the supporting member is determined on the basis of said variables, and further, a cross-directional nip profile of the reeling nip is determined, said nip profile being controlled by adjusting the determined cross-directional tension profile of the supporting member.Type: GrantFiled: June 30, 2005Date of Patent: November 16, 2010Assignee: Metso Paper, Inc.Inventors: Petteri Lannes, Tatu Pitkänen, Ilkka Naatti, Jari Tiitta, Rami Vanninen, Marko Tiilikainen

Patent number: 7799171Abstract: A method and a system to control a reeling profile of a material web reel (30), when, in the forming of a material web reel (30), a web is reeled around a reeling core and when in an adjustment of CD-directional profiles of the web reel, profiling devices (8) have been applied. For adjusting quality profiles and reeling profiles of the web, profiling devices are managed with the help of profile measurings of the roller nip and/or of the profile measurings of the reel (30), which are obtained from the reel-up (2). A measuring device (40) for a measuring of a CD-directional hardness profile of the fiber web reel includes a measuring head (43), which is connected with a loading means (41, 42), which loads the measuring head against the fiber web reel. The motion course of the measuring head is linear.Type: GrantFiled: July 1, 2005Date of Patent: September 21, 2010Assignee: Metso Paper, Inc.Inventors: Tapio Mäenpää, Jari Tiitta, Petteri Lannes, Rami Vanninen, Tatu Pitkänen, Heikki Kettunen, Matti Innala, John Shakespeare, Toni Heikkilä, Topi Tynkkynen, Teppo Kojo, Risto Mäkinen, Marko Tiilikainen, Matti M.

Publication number: 20080140322Abstract: The invention concerns a method and a system in the maintenance of machine components, devices and systems relating to papermaking, where the condition, state and/or performance of machine components, devices and systems relating to papermaking are monitored by monitoring systems, which are used for performing load measurements and for collecting load measurement data comprising load measurement signals. In the method according to the invention, the measured load measurement data is processed in such a way that of the load measurement data one or more load characteristics are formed, which express the load directed at the machine component or device being measured. In the method according to the invention, load characteristics determined in real time are used as input information for an operational reliability model in order to provide an operational reliability model.Type: ApplicationFiled: April 13, 2005Publication date: June 12, 2008Applicant: METSO PAPER, INC.Inventors: Tatu Pitkänen, Petteri Lannes, Rami Vanninen, Jussi Koskelainen, Matti Kemppainen
