The porous material used for the guiding surface enables the line (1) to glide on a fluid pad of less than 1 mm. The losses of fluid on the surfaces not covered by the line (1) are very low.Type: GrantFiled: May 30, 2001Date of Patent: October 21, 2003Assignee: Bachofen & Meier AG MaschinenfabrikInventors: Bruno Holtmann, Konrad Dessovic, José Antonio Mena

Patent number: 6613144Abstract: The invention relates to a device for dosing flowable, preferably thick media, without the use of a pump. The device can preferably be interchanged on the cover or can be fixed as a cover of a common withdrawing device for paper towels, woven fabrics or other fabrics, cotton balls and the like. The inventive device comprises a dispensing container which is either constructed as a cover itself or comprises means for fastening on such a cover. In addition, said container releases a desired quantity of medium located therein when pressure is exerted on a predetermined partial area. The invention is preferably used in the areas of personal hygiene, household cleaning and industry in order to clean, polish and/or lubricate.Type: GrantFiled: February 8, 2001Date of Patent: September 2, 2003Assignee: Kuyus-StiftungInventors: Ulrich Loertscher, Toni Pfluger

Patent number: 6610148Abstract: A catch pan apparatus for starting and stopping coating is disclosed for coating a downwardly moving receiving surface by curtain coating. The catch pan device includes an intercepting pan that intercepts the curtain when coating is stopped and a substantially horizontal intercepting surface that intercepts the curtain only when the catch pan moves to start or stop coating. The intercepting pan and horizontal intercepting surface intersect to create a volume that retains in the catch pan excess liquids that would otherwise spill onto the coating receiving surface as the catch pan is retracted to a non-intercepting position. The catch pan is controllably retracted at high speed through the curtain using linear servomotors such that the releasing edge of the horizontal intercepting surface passes close to the coating receiving surface at the point of curtain release. Flushed edge guides maintaining curtain width are positioned outside the lateral edges of the catch pan.Type: GrantFiled: November 26, 2001Date of Patent: August 26, 2003Assignee: Eastman Kodak CompanyInventors: Kenneth J. Ruschak, Robert J. Deprez

Patent number: 6607145Abstract: In a spray gumming unit, a gumming device is equipped with an ejector that sprays an adhesive substance and that is connected with a shutter element. The shutter element moves towards and away from the ejector between a position where it closes the ejector and in which a pad, fixed to one end of it, is in contact with the ejector, and a position where the ejector is left open. During the movement of the shutter element and of the pad between the ejector open and closed positions, an applicator applies an antiadhesive liquid substance on the pad.Type: GrantFiled: November 1, 2000Date of Patent: August 19, 2003Assignee: G.D S.p.A.Inventors: Silvano Boriani, Alver Tacchi, Alessandro Minarelli

Patent number: 6599364Abstract: An apparatus for applying liquid or pasty application medium, in particular aqueous pigment suspension, to one or both sides of a moving material web, especially to a paper or board web, during its production and/or finishing. The invention provides for the vacuum generating device to be assigned to that side of the material web which faces away from the application medium curtain, at least to the region of incidence of the application medium on the material web.Type: GrantFiled: March 5, 2002Date of Patent: July 29, 2003Assignee: Voith Paper Patent GmbHInventor: Benjamin Méndez-Gallon

Patent number: 6592931Abstract: In a coating method, a precoating layer is applied to one surface of a web W laid between a plurality of web guide rollers GR while a leading end surface of an extrusion-type head portion EX is pressed against the one surface of the web. Accordingly, entrained air increasing as the transferring speed of the web becomes higher could be prevented from entering a coating point on a doctor edge surface near an outlet of a slot by the meniscus of coating liquid formed in a slight gap between the front edge surface of the extrusion-type head portion and the one surface of the web approaching there. As a result, the precoating layer having an excessive amount can be applied stably without turbulence at the coating point caused by the entrained air. Further, coating can be done stably in the rod portion by setting the thickness of the precoating layer for a final coating layer and a virtual coating layer.Type: GrantFiled: October 26, 1999Date of Patent: July 15, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Hideaki Takekuma, Mikio Tomaru

Patent number: 6582518Abstract: A guide system and method for positioning an elongated strand in a liquid dispensing environment. The guide system includes a guide mechanism for supporting and guiding the strand in alignment with a dispensing outlet of a liquid dispenser. The guide mechanism is adjustable along three orthogonal axes. A bead of liquid material is dispensed from the dispensing outlet that is fully or at least partially captured on the strand.Type: GrantFiled: March 23, 2001Date of Patent: June 24, 2003Assignee: Nordson CorporationInventor: John M.

Patent number: 6579366Abstract: A coating machine for directly or indirectly applying a coating to a material web is designed to apply liquid or viscid coating medium onto a moving surface. The coating machine includes a discharge nozzle for discharging a coating medium onto the moving surface. The discharge nozzle has a first nozzle lip residing on the feed-side, and a second nozzle lip residing on the trailing side with respect to the moving surface. At least one of the first and second nozzle lips is composed of a blade element.Type: GrantFiled: January 12, 2001Date of Patent: June 17, 2003Assignee: Voith Paper Patent GmbHInventors: Richard Bernert, Manfred Ueberschär, Eckhard Wozny, Dennis Fartheymüller

Patent number: 6576298Abstract: The interface between a moving conveyor belt and a work piece can be lubricated using an air driven stream of finely divided droplets of a lubricant composition. Droplets of a preferred size are directed by the air stream onto the conveyor with little waste of lubricant off the conveyor. The lubricant provides a very low coefficient of friction and little or no stress cracking in the containers. Using a low pressure and low flow rate air stream in conjunction with a low flow rate liquid lubricant attains the useful particle size in the lubricant add on spray. The liquid lubricant is sheared by the effect of the air flow creating the desirable droplet size and pattern of lubricant on the conveyor.Type: GrantFiled: April 20, 2001Date of Patent: June 10, 2003Assignee: Ecolab Inc.Inventors: Scott Bennett, Kim Person Hei, Minyu Li, Amy Haupert, Keith D.
