Abstract: An application device for applying an application medium to at least one side of a moving product web, the web having a running direction. The application device includes at least one roll supporting the web, at least one pocket between at least one roll and at least one side, at least one pocket having a size and a shape, at least one feed apparatus including a metering element, the metering element having at least one discharge nozzle projecting into at least one pocket and at least one application chamber designed into the metering element, at least one discharge nozzle discharging the application medium onto the web in a first direction and proximate to at least one application chamber, the first direction approximately orthogonal to the running direction.

Abstract: The invention relates to a device for the application of a liquid medium onto at least one side of a moving material web, specifically a cardboard web, including at least one roll and at least one feed device for the coating medium, whereby during operation of the device a liquid sump forms between the roll and the web. Nozzle lips of a nozzle body of the feed device are configured so that the desired dimension of the open surface of the liquid sump and the depth of immersion of the nozzle lips into the liquid sump, and thereby the level of the liquid sump are adjustable. The nozzle lips are surrounded up to 80% of their total length by the liquid sump.

Abstract: The invention relates to a device for the application of a liquid medium onto at least one side of a moving material web, specifically a cardboard web; comprising at least one roll (1; 1a) that supports the web (3) and at least one feed device (5; 5a) for the coating medium, whereby during operation of the device a liquid sump (6; 6a) forms between the roll (1; 1a) and the web (3). According to the invention, the nozzle lips (13, 14; 13a, 14a) of a nozzle body (12, 12a) of the feed device (5, 5a) are configured so that the desired dimension of the open surface of the sump (6, 6a) and the depth of immersion of the nozzle lips (13, 14; 13a, 14a), and thereby the level (P) of the sump (6, 6a) are adjustable. The nozzle lips are surrounded to 80% of their total length—starting from the nozzle opening (15, 15a)—by the sump (6, 6a).

Abstract: The invention is directed to a stationary sliding bar for guiding a paper or cardboard web extends across the entire web width B. Viewed in cross section, the sliding bar has a convex, rounded surface. Due to a relatively high speed of travel of the web, an aerodynamic flotation web forms between the sliding bar and the web.
