ムへの容器の成形に支障を来さない位置である。First, prior to the automatic joining operation, the spare wound succeeding film f 2 is set at a predetermined position (lower side of the preceding fill in this embodiment), and its leading end is set as shown in FIG. 1 [A]. It is pulled out slightly downstream (right side in FIG. 1) from the position of the cutter 2. At this time, the gripping transfer device 4 is waiting in the device U and the gripping transfer device 5 is waiting in the position X. Under such a condition, when the preceding film f 1 is consumed and the end of the preceding film f 1 comes to the position of the detector 6 and the detector 6 detects that, the gripping transfer device 4 is closed by the detection signal and the preceding film f 1 is closed. The film is gripped at the same time as 1 is punched and the part 5b of the gripping transfer device 5 is closed to punch a film in the subsequent film f 2 and at the same time grips the film. At the same time, the cutter 2 is operated to simultaneously cut the films f 1 and f 2 as shown in FIG. 1B. The holes formed in the preceding and succeeding films are located at positions close to both side edges of the film as indicated by p in FIG. 2 [A], and are positions where the formation of the container into the film is not hindered.

By moving, the trailing edge of the preceding film f 1 is aligned with the upstream edge of the joining device 3 and the leading edge of the following film f 2 is aligned with the downstream edge of the joining device 3. In this state, the trailing end of the preceding film f 1 and the leading end of the following film f 2 are overlapped by a predetermined width (in this embodiment, by the width of the joining device 3). Thereafter, as shown in FIG. 1 [D], the upper and lower two parts 3a and 3b of the joining device 3 approach each other to sandwich the overlapped parts of the film and heat-bond them.
