PROBLEM TO BE SOLVED: To provide a correction method and a correction device for the seam-weld zone in a welded can where, at the time when the weld zone in a welded can after electric resistance seam welding is subjected to correction by correction tape, can barrels each composed of a cylindrical body can be stably carried in a fixedly held state in succession, thus the residual correction tape lying in the parts other than the can barrels under carrying can be surely removed by single treatment operation, and influences such as the thickness, width and material of the correction tape are suppressed to attain the improvement in the yield of the correction tape and its capacity in correction treatment. SOLUTION: As can barrels 15 each composed of a metallic cylindrical body or prismatic body opening back and forth are carried in succession while fixedly holding and stabilizing the intervals of the can barrels 15, the joints of the can barrels 15 are heated. Continuously fed correction tape 32 is thermocompression-bonded to the heated joints. The correction tape 32 remaining between the adjoining can barrels 15 is removed and is thereafter subjected to discharging treatment. COPYRIGHT: (C)2005,JPO&NCIPI
