LIQUID LEAKAGE PREVENTING MECHANISM BY ROLLER OF PLATING TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid leakage preventing mechanism by free rollers of a plating treatment device which enables the smooth passage of a sheet-like product between the free rollers and prevents the fall-down of the product from hung jigs. SOLUTION: Product passage channels 5 are formed on both side walls of a tank 3 in which a treating liquid is put. A pair of the rollers 7 and 7 sinking in an upright state in the liquid near the product passage channels 5 in the tank are disposed. Intervening bodies 8 which form a clearance C to reduce the roller grasping pressure applied on the sheet-like product W passed between the rollers are disposed on the lower side of the rollers by overcoming the force to bring the product near to the rollers by the outflow pressure of the liquid on the lower part side of the rollers.
