Patent number: 7429310Abstract: A paper or board machine has a fabric (10) that is adapted mobile as well as rolls (11, 11?) arranged to support the fabric (10). The fabric (10) is tensioned by changing the position of one roll (11?) of the rolls (11, 11?). Correspondingly, the fabric (10) is guided by changing the alignment of one roll (11?) of the said rolls (11, 11?). Surprisingly the fabric (10) is both tensioned and guided by changing the alignment and position of only one and the same roll (11?). In addition, the wrap angle of the fabric (10) at this roll (11?) is set higher than 30°.Type: GrantFiled: May 4, 2004Date of Patent: September 30, 2008Assignee: Metso Paper, Inc.Inventors: Pertti K.

Patent number: 6988398Abstract: A method and a device for tracking the position of the edge of a moving web (12), such as a fabric or a web of a paper machine, in which method a pressure-sensitive sensor element (14) is disposed in/onto the surface of the roll (10) guiding the web (12), which sensor element reacts to the pressure applied to it by the moving web (12) by producing an electric signal, on the basis of which it is possible to determine the exact position of the edge of the web (12) on the roll (10). The band-like sensor element (14) comprises one single sensor strip or several sensor strips (141 . . . 14n) disposed successively in the band.Type: GrantFiled: December 19, 2002Date of Patent: January 24, 2006Assignee: Metso Paper, Inc.Inventors: Jyrki Saloniemi, Samppa J.

Patent number: 6916404Abstract: A method and an apparatus for web threading in a drying section of a paper machine or the like. A leader (24) and a so called run-down strip are formed by cutting in the web coming to the drying cylinder in the drying section. An underpressure box (18) is arranged at the opening gap between the drying cylinder (14) and the drying wire, on that side of the wire which is away from the web, whereby this box can direct against the web an underpressure which is controllable in the machine's cross direction. The underpressure box creates an underpressure region (34?) between the leader and the underpressure box, the region having an underpressure p1 at the detachment point, i.e. in the area where the wire is detached from said drying cylinder (14), which underpressure is sufficient to detach the leader from said drying cylinder.Type: GrantFiled: October 26, 2001Date of Patent: July 12, 2005Assignee: Metso Paper, Inc.Inventors: Antti Komulainen, Kari Juppi, Jorma Laapotti, Reijo Jokinen, Matti Kurki, Juha Lipponen, Markku Lyytinen, Samppa J.

Patent number: 6447646Abstract: The invention relates to a doctor assembly in a paper machine, which is intended to clean, e.g., a roll, and which includes a surface against which a doctor blade is set, a blade support for supporting the doctor blade, a frame, a jointed bearing assembly, which supports the doctor blade and is itself supported from the frame, and which is parallel to the doctor blade, and extends essentially over the entire width of the roll, and loading devices between the blade support and the frame for turning the doctor blade in relation to the frame and for pressing the doctor blade against the surface with a selected pressure. Due to the continuous support, there is essentially no deflection in the doctor assembly, when it is attached by its frame directly to the structures of the paper machine.Type: GrantFiled: July 26, 2001Date of Patent: September 10, 2002Assignee: Metso Paper, Inc.Inventors: Reijo Hassinen, Samppa J.

Patent number: 5695613Abstract: A rib construction for a draining device in a paper machine in which a loading rib is used to support and/or to load a wire or wires in a paper machine and/or to doctor water from the face of a wire or wires. The rib is loaded by pressure of a medium. Between the rib and its frame part, a pressure space is formed and defined by a flexible belt and into the loading pressure is passed into this pressure space. The flexible belt defines the pressure space so that the area of effect of the loading force is independent from the movement of the rib toward the wire(s).Type: GrantFiled: February 27, 1996Date of Patent: December 9, 1997Assignee: Valmet CorporationInventors: Esa Hentila, Jyrki Jaakkola, Samppa J.

Patent number: 5690792Abstract: A set of ribs in a dewatering device in a paper machine which is used to support and/or to load the wire or wires in the paper machine and/or to doctor water from an inner face of a loop of the wire or wires. The set of ribs includes at least two transverse ribs placed one after the other at a distance from one another in the machine direction. The height positions of the ribs are adjustable and the ribs are interconnected in pairs by intermediate parts. The intermediate parts connect to the ribs by mechanisms of four articulated joints placed at a distance from one another in the transverse direction of the wire/wires so that the positions of the ribs in the horizontal direction remaining invariable irrespective of the height positions of the ribs in relation to one another. The intermediate parts and associated articulation mechanism are placed at a distance from one another in the vertical direction.Type: GrantFiled: November 2, 1995Date of Patent: November 25, 1997Assignee: Valmet CorporationInventors: Jyrki Jaakkola, Samppa J.
