くいし、またフイルムの破れも起りにくい。 Conventionally, as shown in FIG. 4, this type of film cylinder making apparatus has a pair of endless chains 2 on both sides of a track for conveying a large number of trays 1, 1, . 2 are provided with a large number of clips 3, 3, . . . respectively, and the clips 3, 3, . has been done. More specifically, while the trays 1, 1... are transported horizontally, the chains 2, 2 are positioned closer to the exit 6 of the film than to the entrance 5 of the film.
While providing an inclination so that
The film is stretched in both directions at the middle part of the chain so that it becomes slightly larger, and then the film is formed into a tube and wrapped around each tray. However, when observing the stretching state of the film in more detail, it was found that the circular parts 9, 9 in FIG. I solved it. Preferably, the entire film is stretched evenly, so that the film is less likely to wrinkle and tear.

れる。 As shown in FIG. 2, the tray T placed on the belt conveyor 10 is conveyed horizontally between the roller receiving members 15, 15 on both sides. On the other hand, when the chains 11, 11 are driven to rotate in the direction of the arrow in FIG. Begin transporting downward at a relatively gentle incline. As shown in FIG. 2, since the upper surface of each roller 16, 16 is installed higher than the tray T, the chain 11,
The film F conveyed by roller 11 is first transported by roller 1.
6 and 16. Since the rollers 16, 16... are disposed in a shape that widens towards the direction of travel of the film F, the middle part of the film F is stretched in both directions by the rolling of the rollers 16, 16, and on the other hand, the middle part of the film F is stretched in both directions. is stretched in both directions due to the expansion of the chains 11, 11 in the direction of movement. And on both sides of the film F are roller receiving materials 1.
5 and 15, it is guided to the underside of the tray T as shown in FIG.

しながらトレイを包装できる効果がある。 As mentioned above, the present invention includes elongated roller receiving members 15, 15 between the conveyor 10 for carrying the tray T and a pair of endless rotating bodies 11, 11 on both sides of the conveyor 10 for transporting the film. At the same time, a large number of rollers 16, 16... are placed on these roller receiving members 15, 15.
Since the rollers are rotatably supported so that the rollers widen toward the transport direction and the upper surface of each roller is slightly higher than the tray T, the upper surface of the packaged items in the tray T comes into contact with the lower surface of the film F. In front, the endless rotating bodies 11, 11 are stretched horizontally by the rolling of the rollers 16, 16...
The entire film is stretched by the spread of
There is an effect that the tray can be wrapped while the entire film is stretched evenly without the portion held by the clips becoming extremely thin or torn.
