って省人性が低くなる。However, such a device has the following drawbacks. (1) Since the collar 011 having a complicated shape is welded to the skewed cylindrical structure 010, a strict left-right symmetry cannot be obtained due to the deformation at that time. Therefore, the sheet-like film 02 meanders at the collar 011. There is a possibility that the mating surfaces 014 and 014 of the both ends do not coincide with each other, and the bag product 08 is insufficiently sealed. (2) Since the pair of guide pieces 013 are provided so as to project on the obliquely-cylinder-shaped structure 010, the production thereof is troublesome, and the economical efficiency is reduced. (3) As a means for correcting the meandering of (1) above, as shown in the partial front view of FIG.
It is known that the support roller 04 is tilted in the left-right direction 016 as shown in the partial front view of FIG. 5B, but this requires a complicated meandering correction mechanism, which increases the manufacturing cost. It is bulky and therefore less economical. Further, since the position of the support roller 04 is separated from the position of the collar 011 on the upstream side, the control reaction is slow, and therefore there is a problem in a device having a high operating speed. (4) Similarly, as means for correcting the meandering in (1) above, as shown in the partial front view of FIG. 6 (C), ring-shaped stoppers 017 are coaxially provided at both ends of the support roller 04. As shown in the partial front view of (D) of the same figure, it is known that the guide stopper 018 is provided on the collar 011 so as to be paired left and right. However, this does not mean that the meandering control is sufficient. There is a performance problem. In addition, the sheet film 0
When the size of 2 is changed, it is necessary to change the position of the guide stopper 018, which makes it difficult to automate the device and thus reduces labor saving.
