METHOD AND DEVICE FOR KEEPING A COATING ROD AND A ROD CRADLEIN A BAR COATER CLEAN AND FOR PREVENTING LEAKAGE OF LUBRICATION AND/OR COOLING WATER

摘要

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 (41) is, supported revolvingly in a rod cradle substantially over its entire length (42). The rod cradle (42) is attached to the frame constructions (50) of the coater. The rod cradle is also provided with at least one groove (43, 44) substantially parallel to the coating rod (41) and open towards said coating rod, in which grooves(s) water is circulated to lubricate, cleanse and/or cool the coating rod (41) and the rod cradle (42). The coating rod (41) is loaded towards the base (B) to be coated by loading the rod cradle (42). The rod cradle (42) and the sealing lips (45, 47) of the rod cradle are loaded so that the loading seals the glide faces (46, 48) between the coating rod (41) and the rod cradle (42) substantially over the entire length of the rod cradle and prevents leakage, or at least substantially reduces leakage, from the water grooves (43, 44). 21
