る。Also, as a film forming device in the packaging device,
As shown in FIG. 14 (front view) and FIG. 14B (side view), there is one in which a rigid guide plate 15 is formed outward from the upper edge portion 4a of the molding cylinder 4. However, the guide plate 15 has an upper edge.
Since it is curved from almost the entire circumference of 4a and extends outward, it is not easy to manufacture, resulting in a high cost device. As a conventional example, as shown in FIG. 15A (front view) and FIG. 15B (side view), the upper edge portion 4 of the molding cylinder 4 is
In some cases, a rigid rib 16 is formed along the outer periphery of a. However, in this conventional example, the forming cylinder 4
It is necessary to install another member on the outer periphery of the upper edge portion 4a and fix it by soldering or the like, which is very difficult to manufacture.

る。Those shown in Figures 14A and 14B as well as Figures 15A and 1
In the case shown in FIG. 5B, since the packaging film is guided by the guide plate 15 or the ribs 16, the film is placed at the upper edge 4a.
Does not slide at an acute angle, and the slip during feeding of the film is improved. However, since the guide plate 15 and the rib 16 are rigid, unevenness is likely to occur in the contact with the supplied packaging film. Therefore, if there is a bias in the tension of the packaging film 1 or a step in the film thickness direction due to the provision of the unsealing piece 11, when the packaging film 1 slides on the guide plate 15 or the rib 16, the width direction of these surfaces is increased. It becomes easy to shift the position. As a result, the edge 1a of the packaging film 1
Problems such as displacement of the position of the overlapping portion with 1b are likely to occur. When the unsealing piece 11 is attached to the packaging film 1, the edge of the unsealing piece 11 has a guide plate 15 or a rib.
It hits 16 edges and is prone to curling and bending.

の弾性力により適度な力により包装フィルム１の下面に
当接して包装フィルム１を案内する。As shown in FIG. 1, the packaging film 1 has a guide roller 3
And the like, and the central portion in the width direction of the packaging film 1 is guided by sliding on the surface of the guide 21 (the surface of the sheet-like material 23). In the portion where the guide 21 is not provided, the packaging film 1 is It is supplied to the inside of the molding cylinder 4 while being guided by the upper edge portion 4a. At this time, the elastic guide 21 comes into contact with the lower surface of the packaging film 1 and guides the packaging film 1 by an appropriate force due to its elastic force.

供給位置のずれなどが生じることがない。Further, since the guide 21 can exert an elastic force by the leaf spring 22, it is pressed against the lower surface of the packaging film 1 by an appropriate force and flexibly follows the packaging film 1. Therefore, even if the supply angle θ of the packaging film 1 fluctuates or the tension of the packaging film 1 fluctuates when the contents are filled, the guide 21 elastically deforms following the fluctuation. The deformation of the guide 21 can cope with the fluctuation of the supply tension of the packaging film 1, and the supply position of the packaging film 1 is not displaced.
