ABSTRACT:
A method and device for keeping a coating rod and a rod cradle in a bar coater clean and for preventing leakage of the lubrication and/or cooling water used in the bar coater is disclosed. The invention is intended for a bar coater in which the coating rod is, supported revolvingly in a rod cradle substantially over its entire length. The rod cradle is attached to the frame constructions of the coater. The rod cradle is also provided with at least one groove substantially parallel to the coating rod and open towards said coating rod, in which grooves(s) water is circulated to lubricate, cleanse and/or cool the coating rod and the rod cradle. The coating rod is loaded towards the base to be coated by loading the rod cradle. The rod cradle and the sealing lips of the rod cradle are loaded so that the loading seals the glide faces between the coating rod and the rod cradle substantially over the entire length of the rod cradle and prevents leakage, or at least substantially reduces leakage, from the water grooves.
