Abstract

A device designed for coating a material web with a coating medium includes a coater, a metering/smoothing device positioned downstream of the coater in the direction of feed of the material web, at a certain distance from the coater, and a support roll around which the material web is guided. Moreover, the material web is guided around the support roll only in the area of the metering/smoothing device, and it traverses essentially in a straight line between the coater and the support roll. In accordance to a first aspect of this invention, a support arrangement supports the material web in the straight web section between the coater and the support roll. In accordance to a second aspect of this invention, devices are provided which stabilize the material web in the area where the web traverses in a straight line.
