Abstract
Method and apparatus for splicing together metal webs with the ends thereof being butted against each other or slightly lapped on each other. In the metal web splicing apparatus, there is provided a reduction roller which comprises a hold portion having a first radius and a projected portion having a second radius slightly greater than the first radius. With use of the reduction roller, while both sides of the weld spliced portion of the metal webs are being held and fixed by the hold portion of the roller, the weld spliced portion is rolled by the projected portion of the roller, thereby preventing escape of the rolled portion.
