The coating bar extends across the machine width and is supported on a cradle substantially over its entire length. The coating bar spreads and smooths a coating agent introduced into the coating device and applied onto the moving base before the moving base contacts the coating bar. The coating bar in accordance with the invention is a smooth bar of large diameter, fitted against the moving base so that the profile of coating quantity of the coating agent can be controlled.
