れている。Attach a heat-shrinkable synthetic resin film with a trademark, a pattern, etc. to the body of a container such as a bottle or can, and use this as a label, or a label / container protective film, and in the case of a bottle, It has been widely practiced in the past to cover the periphery of the stopper at the bottle mouth with a part of the film so as to also serve as a cap seal.

容器に嵌め込む途中で、チューブに腰折れ、めくれ等が
生じ易いという難点がある。As a method of mounting a heat-shrinkable film (hereinafter, “film”) on a container, the film is formed into a tube shape in advance, and after it is fitted around the container, heat-shrinking treatment such as hot air blowing is performed. The method of applying and adhering to the surface of the container has been widely used in the past. However, in this method, a tube (which is usually folded and supplied flatly for convenience of storage and transportation) is fitted into the container. When it is inserted, it requires a relatively difficult and cumbersome operation for expanding the tube from a flatly folded state into a tubular shape, and there is a problem that the tube is likely to be bent or turned over while the tube is being inserted into the container.

ム(F)はついで熱収縮処理に付される。Instead of the above method of fitting the film tube into the container,
Wrap the film around the surface of the container and overlap the front edge and the rear edge of the film, join the overlapping surfaces to form a tube, and heat-shrink it to bring it into close contact with the container surface. Thus, the above-mentioned difficulties can be solved, and at the same time, the step of molding the tube and the step of fitting the tube into the container can be achieved simultaneously as one step on the surface of the container, reducing the number of steps. , Productivity is improved. A method shown in FIG. 8 has been proposed as a method for mounting the film (Japanese Patent Laid-Open No. 60-158025). FIG. 9 shows a film winding step according to the same method. In the figure, (15
(0) is a rotary drum having a vacuum suction hole (151),
0) is a container holder. The container (B) is held by the holding table (160) and substantially abuts on the peripheral surface of the rotary drum (150), and the supporting table (16)
Due to the rotation of (0), the rotating drum (150) is rotating at a peripheral speed equal to the peripheral speed. The film (F) is fed from the film supply roller (170), is fed through the guide roller (180) between the rotary drum (150) and the pressing roller (190) abutting on the peripheral surface thereof, and is fed to the rotary drum (150). ) Is adsorbed and held (FIG. 9 [I]). The film (F) adsorbed and held on the rotating drum (150) is transferred toward the container (B) as the rotating drum (150) rotates, and the front edge portion (F1) of the film (F) is moved to the container (B). When reaching the position of contacting the side surface of B), the front end edge portion (F1) adheres to the side surface of the container (B) by the adhesive force of the adhesive applied to that portion in advance. Front edge
The film (F) having (F1) adhered to the surface of the container (B) is wound around the container (B) while being peeled off from the peripheral surface of the rotating drum (150) as the container (B) rotates. (Fig. 9 [II]). When the container (B) makes one revolution and returns to the position where the front edge (F1) of the film overlaps the rear edge (F2), the front edge (F1) and the rear edge (F2) are overlapped. Are joined (Fig. 9 [III]). The film (F) wound up in the container is then subjected to heat shrinkage treatment.

に隙間のある部分に位置する重ね合わせ面を接合させる
ことができないからである。In the above film mounting method, when the container (B) has a columnar shape having a uniform cross-sectional diameter from the lower part to the upper part, the film can be easily wound around it. However, it is extremely difficult to successfully wrap the film around an irregularly shaped container, such as a gourd-shaped container, a drum-shaped container, or a polished container, which has a recessed portion or a bulged portion and whose sectional diameter changes partially. . That is, unlike the case of the cylindrical container, as shown in FIG. 10, when the film (F) is wound around the irregularly shaped container (B), the container (B) is rotated around the peripheral surface of the rotating drum (150). It is only the bulging part (B1) that the front end edge part (F1) of the film (F) on the rotary drum (150) can be adhered to the container (B) substantially by contacting with the container (B1). Since the engagement state of the film with respect to (B) is extremely unstable, the film is liable to roll over or turn over during winding, and in some cases, the adhesive portion (a) peels off and falls off the container surface. Even if the film (F) can be successfully wrapped around the container, it is not easy to join the overlapping surfaces of the front edge (F1) and the rear edge (F2) of the film (F). . In the case of a cylindrical container, the entire superposed surfaces can be joined by pressing the superposed front end edge (F1) and rear end edge (F2) from the outside to the side surface of the container (B). However, in the case of an irregularly shaped container, only the part facing the bulging part can be pressed and joined to the container, and the overlap is located in the part where there is a gap between the film (F) and the container (B). This is because the mating surfaces cannot be joined.

"Film") (F) the front edge (F1) of the mandrel is sucked and held on the vacuum suction surface of the mandrel, the mandrel (10) suction-held the front edge (F1) of the film
The film is wound around the mandrel by rotating the film about one axis about its axis, and the rear edge (F2) of the film is suction-held on the vacuum suction surface of the mandrel and the front edge of the film is held. The process of superposing on the (F1), the film is formed by joining the superposed surfaces of the front edge (F1) and the rear edge (F2) of the film (F) wound around the mandrel (10). A step of forming into a tube, a step of extracting the mandrel (10) from between the film (F) formed into the tube and the container, and subjecting the film (F) to heat shrinkage treatment.

等、巻き付けの仕損じが生じることはない。According to the present invention, the film is adsorbed and held on the cylindrical mandrel (10) by a vacuum suction force, and is wound around the container by the rotation operation thereof. Therefore, it goes without saying that the container has a cylindrical shape. Even in the case of a container having a different shape, the film (F) does not fall off during the winding process and the winding process is not damaged.

In the process of joining the mating surfaces, the cylindrical mandrel (10) serves as a backing plate, and by pressing the mating surface from the outside to the plate surface of the mandrel, regardless of the presence of irregularities on the container surface, the stacking is performed. The mating surfaces can be joined securely.

Stop the suction of the vacuum suction hole (11) of (10) and film (F)
And pull out the mandrel (10) from between the container (B) and the container (B) on the holding table (50),
Or lower it from the holding table (50) and, as shown in FIG. 6,
When heat shrinking treatment is performed by the hot air blowing device (90), the film (F) is finished in a predetermined mounting mode in which the film (F) is in close contact with the surface of the container (B).

A square tube-shaped mandrel (10) corresponding to the contour is used, and in the winding process of the film (F), the container (B) may be rotated together with the mandrel (10). Also,
When the front edge (F1) and the rear edge (F2) after winding the film (F) on the mandrel (10) are bonded by using an adhesive instead of the above heat fusion There is also. In that case,
After applying an adhesive between the overlapping surfaces of the film (F) using an appropriate adhesive applying jig, the overlapping surfaces are pressed by a pressing device (80) (of course, the pressing surface portion (81) in that case is a heater). Need not be built in).
