Abstract
A method of splicing together metal webs for use in planography with the ends thereof being butted or lapped against each other. In the metal web splicing method, the ends of the metal webs are spliced together in a butted manner, the spliced portion thereof is welded, and the welded spliced portion is rolled. According to the splicing method, there is no level difference in the welded spliced portion, which eliminates the possibility of the spliced metal webs being broken during the movement thereof and also has no adverse effect on the coating process for the spliced metal webs.
