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.

Method and device for coating a size-press roll, paper, or board

A coating bar for a bar coater, wherein the coating bar is supported substantially over its entire length revolving in a cradle fixed to the frame of the coater. The coating bar is profiled and surface-treated by boronizing so that a layer of iron boride is applied to the profiled surface of the coating bar.
