摘要： A fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move away from one side of the sheet that is toward the curved surface, so that the one side is relatively free of entrained air. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact the web surface primarily with the one relatively air-free side of the coating liquid sheet to decrease the occurrence of skip coating on the web surface, especially when the web is traveling past the applicator at high speeds. The coating is applied in excess onto the web surface and is metered and leveled to a desired coat weight by a downstream doctor. The downstream doctor may comprise a single metering device, or it may comprise an intermediate metering device followed by a final metering and leveling device.

摘要： An assembly, for preventing striping in an applicator used for coating a paper or paperboard web, comprising a doctor blade suitable for metering and smoothing a coat to be applied, a cross-machine elongated application chamber adapted immediately in front of the doctor blade, one of the sides of the chamber being formed by the web being coated. A flexible leading blade forming a front sealing edge of the chamber has a perforated stem with openings to allow coating mix from the application chamber to travel in front of the leading blade. A homogenizing chamber is formed in front of the openings in the leading blade using a dam lip or similar flow barrier. The flow exiting the openings of the leading blade is homogenized in the homogenizing chamber as the flow impinges against the flow barrier.

摘要： Apparatus for applying coating liquid to a web of paper traveling over a web supporting surface at speeds of 3,000 or more feet per minute to produce a coated web free of streaking and other imperfections includes the structural elements for distributing coating liquid onto the supported web through a limited application zone within a short dwell time of the liquid on the web, the web moving through the application zone at a speed that is sufficiently high to create turbulence in the coating liquid being applied to the web, doctoring the coating liquid on the web by biasing a primary doctor against the coated web at the rear edge of the application zone so as to form a layer of coating liquid on the web as the web leaves the application zone, the turbulence in the coating liquid causing machine direction streaks in the layer of the coating liquid as the web leaves the application zone; and, at a location downstream and isolated from the application zone, performing a successive doctoring of excess coating liquid on the supported web by biasing a final doctor blade against the coated web to remove excess coating from the web and to level and smooth the coating retained on the web to a final wet film thickness and smoothness.

摘要： A short dwell coater apparatus is disclosed for applying coating material onto a web guided by a backing roll. The apparatus includes a coater housing which is disposed in close proximity to the backing roll. The arrangement is such that the web guided by the backing roll moves between the backing roll and the housing. The housing defines an application chamber which is open towards the web and which extends along the web in a cross-machine direction. The application chamber is connected to a source of coating material such that the coating material is applied to the web during movement of the web past the chamber. The coater housing has an upstream lip which is disposed upstream relative to the chamber and adjacent to the web. The lip defines an upstream coating overflow for permitting excess coating material to flow therethrough. A flexible coater metering blade is disposed downstream relative to the chamber. The blade extends from the housing towards the web for metering the coating material applied to the web. A perforate conduit is disposed within the chamber and extends in a cross-machine direction. The conduit permits the flow therethrough of a vortex of entrained air generated within the chamber such that in use of the apparatus, when the vortex of entrained air is generated within the chamber, the air flows through the perforate conduit away from the chamber so that streaking of the coating material due to the intermittent escape of the entrained air past the metering blade is inhibited.

摘要： A short dwell coater apparatus is disclosed for the application of coating material to a web which is supported by a backing member. The apparatus includes a housing which is disposed closely adjacent to the backing member such that the web moves between the housing and the backing member. The housing defines an application zone which is connected to a pressurized source of the coating material. The application zone has an open face towards the web. A blade is adjustably secured to the housing and extends from the housing towards the web. The blade defines a downstream extremity of the application zone. A movable flow divider supported by the housing extends into the application zone. The divider has an upstream and a downstream end, with the downstream end being movably disposed in the vicinity of the blade for reducing the size of a flow vortex generated within the application zone due to movement of the web past the open face.

摘要： Method and apparatus for coating a paper or paper board web including preventing deposition and drying of the coating paste on the edge zones of the coating chamber by continuously causing a flow of coating paste from the coating chamber past the edge seal (2). Each edge seal is disposed in the space between the front and the rear walls (3,4) of the coating apparatus, and the upper part (11) of each edge seal corresponds to the form of a wedge between the wiping member (9) of the coating apparatus and the web (12) to be coated. Coating paste flows through gaps (13, 14) between the edge seals and the wiping member and between the edge seals and the web, which gaps are for example, between about 2-5 mm wide.

摘要： An end dam for use in a coater head which applies a coating material under pressure from a reservoir onto a web is shown to include an attachment arrangement for attaching the end dam to the coater head a first wall which prevents the lateral movement of the coating material, thereby defining one end of the reservoir, a second wall, spaced from the first wall and laterally away from the reservoir, such that a channel is formed therebetween so that coating material passing over the first wall experiences a drop in pressure sufficient to maintain the coating material within the channel.

摘要： A device for coating a web of material that travels around a backing roller, with a coating chamber that opens toward the backing roller, and with a liquid-coating intake that has an overflow gap at the paper-intake end and is closed off by a metering unit at the paper-exit end. The coating device allows establishment of a wider range of coating densities (e.g. 4-20 g/m.sup.2) without great expenditure and without coating defects in the coating. The metering unit accordingly pivots independently of the coating chamber (3) around an axis that parallels that of the backing roller and is sealed off by a sealing structure (12) from the structure (6) that demarcates the coating chamber.

摘要： A coating apparatus is disclosed for applying a coating onto a surface of a moving web. The apparatus includes a backing member which defines a perforate surface such that when the member is connected to a source of partial vacuum, the web is drawn towards the perforate surface of the member. A coating blade is disposed adjacent to the backing member such that the blade urges the web towards the perforate surface. A permeable belt extends around the backing member with the belt being disposed between the web and the backing member such that when the source of partial vacuum is connected to the backing member, air flows through the belt and the perforate surface for drawing the web into close conformity with the belt. The belt and the web then move together in the same direction for inhibiting the buildup of deleterious material adjacent to the blade that would otherwise remain adjacent to the blade causing marking of the coating applied to the surface of the web by the blade.
