Patent number: 8366878Abstract: A structuring layer of a structuring belt for structuring a wet fibrous web in a press section of a tissue papermaking machine for manufacturing high bulk tissue paper, the structuring layer having a web-carrying side with a surface for cooperating with the fibrous web, the surface having depressions distributed over the web-carrying side and forming a three-dimensional structure of the surface. The depressions altogether constitute 20-80% of the surface. Each depression has a dimension l of 0.25-2.5 mm in a first direction in the plane of the top surface area, a dimension b of 0.25-2.0 mm in a second direction in the plane of the top surface area, such directions being at right angles to each other, a mean depth d of 0.05-0.6 mm, and an area a as measured in the plane of the top surface area of 0.063-5.0 mm2.Type: GrantFiled: July 9, 2012Date of Patent: February 5, 2013Assignee: Albany International Corp.Inventors: Ingvar Berndt Erik Klerelid, Ola Thomasson, Bo-Christer Aberg, Cary P Johnson, John J LaFond

Patent number: 8246782Abstract: An apparatus for transferring a wet paper web from a press nip to a drying cylinder of a papermaking machine, and for structuring the web, includes an impermeable transfer belt that passes through the press nip along with the paper web, and a permeable structuring fabric for transfer of the web onto the drying cylinder, the structuring fabric being arranged in a loop within which a suction transfer device is disposed. A web-contacting surface of the belt has a non-uniform distribution of microscopic-scale depressions, and a suction zone of the transfer device includes a transfer point spaced a distance D from the press nip. The belt is arranged to bring the web into contact with the structuring fabric in the suction zone for a length L, such that suction is exerted on the paper web to transfer the paper web from the belt onto the structuring fabric at the transfer point.Type: GrantFiled: November 4, 2011Date of Patent: August 21, 2012Assignee: Metso Paper Karlstad ABInventors: Paul Douglas Beuther, Frank Stephen Hada, Jeffrey Dean Holz, Hans Ivarsson, Ingvar Berndt Erik Klerelid, Johan Ulf Ragard

Patent number: 8206555Abstract: A papermaking machine for making paper includes a forming section, a press section, and a drying section. The paper web is pressed between two press members while enclosed between a press felt and a transfer belt having non-uniformly distributed microscopic depressions in its surface, the web following the transfer belt from the press to a transfer point at which the web is transferred via a suction transfer device onto a structuring fabric, the web then being dried on a drying cylinder. The transfer point is spaced a distance D from the press nip selected based on machine speed, a basis weight of the web, and the surface characteristics of the transfer belt, such that within the distance D a thin water film between the web and the transfer belt at least partially dissipates to allow the web to be separated from the transfer belt.Type: GrantFiled: December 1, 2011Date of Patent: June 26, 2012Assignee: Metso Paper Karlstad ABInventors: Ingvar Berndt Erik Klerelid, Hans Ivarsson, Johan Ulf Ragard, Frank Stephen Hada, Paul Douglas Beuther, Jeffrey Dean Holz

Patent number: 7166193Abstract: A method of ensuring the flatness of a vane that is mounted in a headbox by means of a mounting arrangement including engagement dowels for cooperation with a downstream support wall of a transverse groove, said vane being affected during operation by shearing forces from the stock and by retaining forces from the mounting arrangement. In accordance with the invention outer engagement dowels are mounted at the side edges of the vane to cooperate during a specific period of time, as the only engagement dowels with the downstream support wall in order to take up said shearing forces, whereby tensile stresses will arise in the downstream end portion of the vane in the cross machine direction.Type: GrantFiled: November 30, 2004Date of Patent: January 23, 2007Assignee: Metso Paper Karlstad ABInventors: Jan Anders Erikson, Tord Gustav Gustavsson, Ingvar Berndt Erik Klerelid, Joakim Norrman

Patent number: 7112258Abstract: A dry end section for a paper-making machine for producing a high-bulk tissue is provided. Such a machine comprises a through-air dryer adapted to finally dry a paper web and a through-air drying fabric configured to transport the web through the through-air dryer. A separating device is included for facilitating separation of the web from the through-air drying fabric. A reel is also provided and is configured to receive the web thereon. The web is received directly on the separating device or on a fabric wrapped about the separating device. In some instances, the web may be compressed between the separating device and an adjacent roll or by a web-compressing device disposed along the fabric transporting the web. The web is then transported to the reel directly from the fabric or other support mechanism extending between the separating device and the reel, without free draw of the web. Associated methods are also provided.Type: GrantFiled: March 18, 2004Date of Patent: September 26, 2006Assignee: Metso Paper Karlstad Aktiebolag (AB)Inventors: Ingvar Berndt Erik Klerelid, Lars-Erik Roland Önnerlöv, Leif Sören Videgren
