Abstract
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.
