PURPOSE:To plate a pressure roll at a high efficiency and high performance by successively providing a vertical type electrolytically degreasing tank, an alkali rinsing tank, a plating tank and a plating rinsing tank and traveling a transfer placing machine for hanging the pressure roll to the upper parts of the respective tanks. CONSTITUTION:A vertical type electrolytically degreasing tank 3, an alkali rinsing tank 4, a plating tank 5 and a plating rinsing tank 6 are buried rectilinearly and successively at intervals of about 5m to the lower part having water level lower than the floor level L of a building of a roll plating equipment. Further a trestle 8 is provided to the upper parts of the respective tanks and a freely elevatable transfer placing machine 2 for hanging a pressure roll is traveled. ln this constitution, the pressure roll 1 is hung by the freely elevatable transfer placing machine 2 and traveled on the trestle 8 in a roll hanging place 7. The pressure-roll 1 is successively immersed in the tank 3, the tank 4, the tank 5 and the tank 6 and treatment is performed. Thereby plating thickness on the surface of the roll is uniformed and efficiency of plating work is enhanced. |
