    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： A coating apparatus and method is disclosed for applying coating material onto a web supported by a backing member. The apparatus includes a housing which is disposed closely adjacent to the backing member. The arrangement is such that the web supported by the backing member moves between the backing member and the housing. The housing defines a chamber having an open end facing towards the backing member. A coating shoe slidably cooperates with the web, the shoe being movably disposed within the chamber. The shoe defines a cavity which is connected to a source of pressurized coating material. The cavity has an exposed face towards the web such that the coating material flows into the cavity and through the exposed face for applying the material onto the web.

    摘要： A short dwell coater apparatus is disclosed for applying coating material to a web supported by a backing member. The apparatus includes a housing which defines an application zone having an upstream and a downstream end. The application zone extends in a cross-machine direction across the web and is connected to a source of the coating material such that the coating material is applied to the web during movement of the web past the application zone. An elongate pipe is disposed within the application zone and extends in a cross-machine direction across the application zone. The pipe defines at least one orifice for the passage therethrough of the coating material. The pipe is connected to the source of coating material such that the coating material flows through the pipe and through the orifice for supplying coating material to the application zone. A vane is rigidly secured to the pipe and extends in a machine direction away from the pipe towards the web such that coating material supplied through the orifice generates a hydrodynamic wedge between the vane and the web for reducing entrained air vortices within the application zone. A metering blade is disposed adjacent to the downstream end of the application zone for metering excess coating from the web.

    摘要： A method and device for coating a web (2) of material, especially a web of paper or cardboard, traveling over a backing roll (1) wherein coating is applied to the web is excess and reduced by a flow-control component (3), especially a doctor, to the desired thickness and wherein the flow-control component is secured to a beam (5) that extends over the operating width. The coating-thickness deviation from a straight line is determined over the operating width and employed as a parameter for controlling the heat emitted by a heater (16), especially heating strips, positioned on the side of the doctor beam facing away from the backing roller.

    摘要： An applicator head is positioned beneath a backing roll over which a substrate can be drawn. The applicator head has a housing which contains a pond of coating material between an up machine overflow lip and a down machine extraction plate or premetering plate. Coating material at a relatively low velocity flows into the pond adjacent to the overflow lip. The premetering plate extends radially from the coating inlet to a position proximate to and converging with the backing roll, where it premeters the amount of coating applied to the substrate. The premetering plate preferably has a plurality of holes through which coating and air are drawn. A metering element is spaced downstream of the premetering plate, and a low pressure area is constructed therebetween. Air and coating are drawn from the low pressure area through a valve, and the pressure thereby controlled.
