ABSTRACT:
The invention relates to a coating method and device for coating a size-press roll, paper or board or a corresponding moving base. The coating device comprises a revolving coating bar which rests against the moving base and extends across the machine width. The coating bar is supported in a cradle substantially over its entire length and is a large-diameter grooved bar fitted against the moving base. The coating bar spreads and smoothes a coating agent onto the moving base. The coating agent is introduced into the coating device in advance of the coating bar in the running direction of the moving base.
