Patent number: 6382100Abstract: A roller assembly positioned downstream of a printing station in a web-fed rotary printing press for pneumatically guiding a web of paper after it has been printed upon, without the risk of smearing the printings. The assembly includes a roller in the form of a hollow cylinder defining a plenum chamber therein and having formed in its surface a multiplicity of air outlet openings in communication with the plenum chamber. Air supplied under pressure to the chamber is therefore expelled from the air outlet openings in order to avoid contact with the roller the web traveling over the rollera baffle encloses at least part of the circumferential part of the roller surface for confining the air being expelled from said at least part of the other circumferential part of the roller surface and for redirecting the confined air into a pair of spaces, spaced, between the web and the roller.Type: GrantFiled: August 18, 2000Date of Patent: May 7, 2002Assignee: Kabushiki Kaisha Tokyo Kikai SeisakushoInventors: Masayoshi Satoh, Yosuke Nobuta

Patent number: 6298577Abstract: A device for enhancing removal of liquid from fabric utilizing mechanical and aerodynamic techniques. A base plate contains one or more apertures to which a vacuum is applied for extracting water from the fabric. The total cross-sectional area of the apertures is selected to be that which will increase, and preferably maximize, the extraction power for the vacuum motor with which said base plate is to be utilized. The number and shape of the apertures is selected to reduce the ratio of the total distance along all the perimeters of said apertures to the total cross-sectional area of said apertures in order to reduce boundary layer drag. The cross-sectional area of each of said apertures is selected to be large enough to permit solid contaminants that can be expected to be in the liquid to pass through said apertures without clogging said apertures. Barriers are attached to the bottom of the base plate to force any liquid in the fabric toward the apertures as the base plate is moved across the fabric.Type: GrantFiled: July 19, 1999Date of Patent: October 9, 2001Assignee: Concept Cleaning Systems, Inc.Inventor: Dan Haynie

Patent number: 6293031Abstract: Method and apparatus for drying a coated paper web (W) or the like web. The apparatus (10) comprises sequentially in the running direction of the web—a turning device (16) arranged on the first side of the web and provided with blow nozzles (20), with which the running direction of the web to be dried is turned in a non-contacting way, and web drying devices (30, 30′) arranged on the first and the second sides of the web, in which the web is dried in a non-contacting manner. The apparatus further comprises a counterpart (18) provided with overpressure nozzles (24), arranged on the second side of the web at the point of the turning device (16), for stabilizing the web run by means of blows generating a local overpressure between the web (W) and the carrier surfaces of the overpressure nozzles (24).Type: GrantFiled: February 1, 2000Date of Patent: September 25, 2001Assignee: Metso Paper, Inc.Inventors: Knut Ringbom, Richard Solin

Patent number: 6289607Abstract: A method and flotation dryer unit effects drying of a web such as a coated paper web. The flotation dryer unit advantageously includes several nozzle boxes extending across the web for feeding drying air toward the web to be dried, a distribution chamber for drying air for leading the dry air into the nozzle boxes, and a suction chamber for gathering the drying air led toward the web from the web area and for directing it to the side of the web. The suction chamber is divided into an equalizing space and an air transport chamber by a perforated plate for equalizing the return air flow occurring from the web area.Type: GrantFiled: November 26, 1999Date of Patent: September 18, 2001Assignee: Metso Paper, Inc.Inventors: Rami Aaltonen, Roland Banecki, Pertti Heikkila, Bertel Karlstedt, Richard Solin

Patent number: 6266892Abstract: A device for enhancing removal of liquid from fabric, such as a vacuum head device for removing liquid from carpet, includes an elongated base plate to be moved across the carpet. The vacuum head has a tapering cross section with a wider upper end and a narrower lower end configured to penetrate into the carpeted surface. In addition, a plurality of apertures are formed in an array in the base plate to withdraw the fluid under a vacuum force. Preferably, the plurality of apertures are sized larger than a width of the lower surface to create a plurality of protrusions extending from the base plate configured to penetrate the carpeted surface.Type: GrantFiled: July 17, 2000Date of Patent: July 31, 2001Assignee: Concept Cleaning Systems, Inc.Inventor: Dan Haynie

Patent number: 6230422Abstract: A method and apparatus achieve a more sustainable lift of a wet or heavy pulp web from a pulp machine to the topmost drying level of a pulp drying, allowing the speed of production to be increased and runnability problems to be minimized. The pulp web is lifted from the last press of the pulp machine to the topmost of the drying levels of the pulp dryer by supporting the web on a support wire. The pulp may be passed through the topmost drying level, and one or two other levels, also supported by a support wire, but in subsequent levels the pulp web is preferably supported only by an air cushion. In each level drying gas is blown toward the pulp web (preferably from both above and below the web) to effect drying, and the web passes around turning rolls between each drying level to enter the next, lower, drying level. The support wire may be of metal or plastic, and has a texture significantly coarser than the texture of wires commonly used in pulp machines.Type: GrantFiled: January 27, 2000Date of Patent: May 15, 2001Assignee: Metso Paper, Inc.Inventor: Paavo Sairanen
