<p>The invention concerns a coating device for coating of a size-press roll, paper or board or of an equivalent moving base. The coating device comprises a revolving coating bar (11, 21), which rests against the moving base (4, 5) and extends across the machine width, and which is supported in a cradle (12, 22) substantially over its entire length. The coating bar is fitted to spread and to smooth the coating agent onto the moving base (4, 5), which said coating agent was introduced into the coating device (10, 20), in the direction of running of the moving base (4, 5), before the coating bar (11, 21). The coating bar (11, 21) is a smooth bar of large diameter and comprises a bar body of small diameter, onto which an outer layer has been provided, so that the profile of coating quantity can be regulated under control. <IMAGE></p> |
