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: 20100032118Abstract: The invention relates to a measuring roll for a fibre-web machine, which roll has a shell on whose surface a sensor is arranged, and which roll is coated with a coating layer proper. The roll comprises at least one protective coating layer placed under the coating layer proper and on top of the sensor in such a way that when the coating layer proper is replaced, the protective coating layer remains substantially on top of the sensor and the roll shell when the coating layer proper is removed. The invention also relates to a method for coating a measuring roll of a fibre-web machine and to a method for replacing a coating of a measuring roll of a fibre-web machine.Type: ApplicationFiled: December 4, 2007Publication date: February 11, 2010Inventors: Petteri Lannes, Tatu Pitkanen, Jari Tiitta, Marko Tiilikainen, Teppo Kojo, Reijo Huuskonen

Patent number: 7584674Abstract: A method for measuring a nip pressure and/or a pressure profile is provided, wherein a nip-forming roll is fitted with a pressure sensor under a coating layer which is protective and functions as a spring on top of the sensor, and the nip pressure delivers to the bottom surface of the coating a deformation proportional to the nip pressure and the deformation compresses the sensor, which responds to the deformation by generating an electric signal.Type: GrantFiled: July 16, 2007Date of Patent: September 8, 2009Assignee: Metso Paper, Inc.Inventors: Matti Innala, Tatu Pitkänen, Petteri Lannes, Topi Tynkkynen, Petri Päivä, Marko Tiilikainen

Patent number: 7449671Abstract: In a method and an apparatus for controlling reeling used in connection with the making of paper/board/some equivalent web-like material, a reeler is used in the reeling which has a reeling element (2), a reeling core (T), around which the web (W) is reeled to form a reel (3), as well as elements for loading the reeling core (T) and the reeling element (2) against each other in order to bring about a reeling nip (N) in between the reeling element (2) and the reel (3). The reeling is monitored by a detection apparatus, which automatically detects any events differing from normal reeling.Type: GrantFiled: April 5, 2005Date of Patent: November 11, 2008Assignee: Metso Paper, Inc.Inventors: Petri Asikainen, Marko Tiilikainen, Toni Heikkilä, Petteri Lannes, Tatu Pitkänen, Marko Rintanen, Petri Enwald

Patent number: 7444862Abstract: A method and a roll for measuring a tension profile is provided. The roll has planted on its surface a spirally helical pressure-sensitive film sensor, such as an EMFi pressure-sensitive film sensor, which makes contact with a web obliquely and which, co-directionally with the web, has a measuring range which is substantially equal to or shorter than a web overlap angle when the roll is used for measuring a lateral tension profile of the web.Type: GrantFiled: July 16, 2007Date of Patent: November 4, 2008Assignee: Metso Paper, Inc.Inventors: Matti Innala, Jorma Kinnunen, Jussi Koskelainen, Tatu Pitkänen, Petteri Lannes, Markus Nylund, Marko Tiilikainen, Jyrki Saloniemi, Reijo Huuskonen

Publication number: 20080251628Abstract: The invention relates to a method and an apparatus in reeling up, in which a paper web or the like (W) is reeled around a center-driven reel spool (5), which is transferred from the primary reeling to the secondary reeling, in which reeling the reel spool (5) is transferred in accordance with the growth of the reel by means of a transfer device (7) at least at some stage of the reeling and the web is brought at said stage from below the reel spool (5) via a reeling nip (N1) formed by the reel spool (5) and a loop (1) of an endless supporting member. According to the invention the web (W) is guided around the reel spool (5) during the reeling via an auxiliary nip (N2) formed by means of the reel spool (5) and the roll (10, 10?).Type: ApplicationFiled: February 11, 2005Publication date: October 16, 2008Inventors: Matti Kemppainen, Vesa Riihela, Teppo Kojo, Risto Makinen, Ilkka Naatti, Marko Tiilikainen

Patent number: 7255000Abstract: In paper and board machines the position of a rolling device relative to another rolling device and/or the force exerted by the rolling device on the other rolling device or any variable acting on these is measured, and the value of the measured variable is compared with the set value of said variable in order to obtain the difference value of the variable, and the position of the rolling device and/or the force it exerts on the other rolling device is controlled on the basis of the difference value. The fluid pressure of the hydraulic means (5) and/or the flow velocity of the fluid to the hydraulic means is changed in order to alter the difference value of the variable by opening and/or closing at least one digital valve in a digital valve pack (7) functionally connected to the hydraulic means (S).Type: GrantFiled: November 13, 2003Date of Patent: August 14, 2007Assignee: Metso Paper, Inc.Inventors: Tatu Pitkänen, Petteri Lannes, Marko Tiilikainen
