First reversing rolls and second reversing rolls are located above the vacuum end of the tank and third reversing rolls and fourth reversing rolls are located above the open end of the tank. Two endless belts extend from the first roll to the second roll, and extend from the second roll to the third roll via the intermediate roll, and extended from the third roll to the fourth roll, and are return to the first roll via the intermediate roll. The endless belts have means for separably joining both the side edges of one endless belt to that of the other. A steel strip is inserted into the gap between the endless belts at any one pair of reversing rolls located in an upstream side, and is released from any one pair of reversing rolls located in a down stream side.
