The apparatus for welding a strip of tape to film includes a tape feed roller for feeding the film continuously and a welding roller disposed in a position where the film is held between both the rollers, both the rollers being rotated in synchronism with each other. The tape is held onto the outside periphery of the tape feed roller and is cut into a strip by a cutting member. The tape is fed to be overlapped on the film while being held onto the tape feed roller. The film and the tape are held between the tape feed roller and the welding roller and the tape is welded to the film in spaced manner by a welding member provided with the welding roller.
