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.

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

Publication number: 20070023561Abstract: A belt reeler has a reeling nip (7) formed by a reeling core (6) or a growing machine reel (4) and at least one endless supporting member (3) traveling at least via a first wire guiding roll (1), and a second wire guiding roll (2). Several parameters of the belt reeler are adjusted simultaneously to adjust the reeling process, of which parameters at least the first parameter and the second parameter are one of the following: web tension (P1), wire tension (P2), distance of the machine reel from the wire turning roll (P3), depression of the wire/machine reel (P4), surface draw (P5, P5?, P5?), and peripheral force (P6).Type: ApplicationFiled: July 3, 2006Publication date: February 1, 2007Inventors: Matti Kemppainen, Jari Tiitta, Vesa Riihela, Topi Tynkkynen, Teppo Kojo, Risto Makinen, Marko Tiilikainen, Ilkka Naatti

Publication number: 20060175456Abstract: Before a reel change a new core (5) is brought to a change station. When the old reel (R) is full, the web is changed to travel to the new core periphery and primary reeling beings. The web forms a reel through a reeling nip (N1) between the loop of an endless supporting member (1) and the core. A change is made to secondary reeling, where a portion of the supporting member (1) brings the web to the reel, to move over to the reel in a nip (N) between said portion and the reel outer periphery. The core (5) is transferred so the nip (N) moves forward. A first guide roll (2) is transferred towards the core periphery so the distance of the nip (N1) located between the core (5) and the loop of the supporting member (1) from the first guide roll (2) changes in the primary reeling.Type: ApplicationFiled: June 10, 2004Publication date: August 10, 2006Inventors: Ilkka Naatti, Teppo Kojo, Risto Makinen, Vesa Riihela, Matti Kemppainen, Olli Tuominen, Topi Tynkkynen
