Abstract

The invention concerns a method for keeping the coating-bar cradle in a bar coater clean in a bar coater in which the coating bar is substantially over its entire length supported revolvingly in a bar cradle (18) fixed to the frame of the coater, which cradle is provided with one or several water grooves (5) substantially parallel to the coating bar and open towards said coating bar. According to the invention, at least one of the water grooves (5) in the bar cradle (18) is kept open constantly and forcibly by promoting the flow in the water groove (5) by means of negative pressure connected to the outlet side of the water. The invention also concerns an equipment by whose means the cradle of the coating bar is kept clean constantly. <IMAGE>
