Abstract

A method of joining strip-shaped sheets includes a support step of placing a support member in contact with a reverse feed direction end of a strip-shaped sheet fed to a pressing machine and a feed direction end of a new strip-shaped sheet, and a joining step of joining the new strip-shaped sheet to the strip-shaped sheet by attaching a tape on the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet, wherein in the joining step, the tape is attached from a side opposite the support member with the support member placed in contact with the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet. The problem of the variation in welding quality encountered when welding thin and wide strip-shaped sheets together is resolved and the strip-shaped sheet is fed smoothly.
