で有利である。Next, a method for manufacturing the film package of the present invention using the apparatus shown in FIG. 4 will be explained. The adhesive tape 4'' pulled out from the adhesive tape supply mechanism 11 is
In other words, the guiding means 1 is applied with such tension that the adhesive tape does not stretch.
5 to the outer peripheral surface of a rotating body (rotating drum) 12. The circumference of the rotating body 12 is preferably formed to be an integral multiple of the cutting length of the adhesive tape. A large number of suction holes 16 are provided on the surface of the rotating body 12, and by reducing the pressure inside the rotating body, the adhesive tape 4 can be temporarily held on the surface by suction. An adhesive tape 4 is held on the outer peripheral surface of the rotating body 12 with the adhesive surface facing outward.
The tape w is cut into a predetermined length by an adhesive tape cutting means 7 equipped with a blade 7' by reciprocating the blade 7' along the wall surface 20 of the rotary body recess 19.
It moves downward according to the rotation of. During this movement, the folded cup 17 housed in the recess 19 of the rotating body 12 rotates in the rotational direction of the rotating body 12 around the rotating shaft 18 due to its own weight and is reversed. do. At this time, the end portion of the adhesive tape piece 4 on the folded cup 17 is folded back toward the adhesive side and pasted together with the adhesive surfaces to form a grip portion 6 (see FIGS. 1 and 2). Then, the folded cup 17 (
(not shown) is pressed by touching the guide plate 21 provided close to it as the rotating body 12 rotates,
The rotating body 12 is returned to its original recess 19 and accommodated therein. In addition to the method shown here, such a method of reversing and returning and storing the folding cup 17 may also be a combination of, for example, reversing using a cam mechanism provided on a rotating body and returning and storing using a spring. This combination of a cam mechanism and a spring is advantageous when a high rotational speed of the rotating body 12 is desired, since reliable operation can be achieved without damaging the device.

ルム上に線状に延在するように行われる。On the other hand, below the rotating body (rotating drum) 12, the wearing film 2 made of a raw material 22 and the packaged object 23 are sequentially conveyed by the film transport mechanism 13 and the packaged object transport device 24. Packaging film = 8 The film 2 is intermittently damaged by the device 25 per package.
Cutting line corresponding to one location (e.g. U-shaped hole)
is bored, guided directly below the rotating body 12, and further pushed up by the reciprocating mechanism (elevating mechanism) 14 so as to come into contact with the outer peripheral surface of the rotating body 12. At this time, the adhesive tape piece 4, which is suction-held with a tab on the outer circumferential surface of the rotating body 12, has rotated to the lower side of the rotating body 12, so the packaging film 2 is being pushed up. The tearing cut line 3 is transferred in synchronization with the position approximately in the center of the tape portion 3 covered with the tape portion near the tab portion 6. This synchronization is
The damage is done by adjusting the time lag between the operation of the device 25 and the operation of the reciprocating mechanism 14. The above-mentioned transfer is carried out by the contact pressure between the rotating body 12 and the pressure roll 26 that rotates in the opposite direction, and the adhesive tape piece 4 on the outer peripheral surface of the rotating body 12 is transferred to the packaging film 2.
The adhesive tape piece 4 is transferred onto the film so that it extends linearly on the film.

得られる。Next, the packaging film 2 whose tearing score line 3 is covered with the adhesive tape piece 4 having the tab portion 6 in this way is cut into 7 pieces.
At the bottom of the ohming 27, the edges on both sides are bent into a cylindrical shape in the direction that they overlap, and with the object to be packaged 23 inside, the bottom shaped part is sealed with tape 28, and then the tip of the package is cut. By cutting and sealing with the tape 29, a package 1 tightly covered with a film is obtained.

で、包装体としての商品価値を低下させることもない。As described above, according to the technique of the present invention, adhesive tape pieces 4 cut to a predetermined length are temporarily held on the outer circumferential surface of the rotating body (rotating drum) 12, and the packaging film 2 is sequentially held from the leading end thereof. In order to transfer and attach the adhesive tape piece 4 in the longitudinal direction of the packaging film 2 while rotating the rotating body 12, the adhesive tape piece 4 that has been cut securely is attached onto the film. As a result, the adhesive tape pieces 4, which were cut and placed intermittently, were connected at incompletely cut adhesive tape parts, which caused the problem in the past, and the packaging film was pulled together. There are no problems that would disrupt the subsequent packaging process. In addition, since the elongation in the length direction due to the tension that tends to remain in the adhesive tape is completely alleviated, there is no possibility of film wrinkles on the sides of the adhesive tape, and furthermore, the bonding position of the adhesive tape grip part 6 can be adjusted. Since there is no discrepancy, the commercial value of the package will not be reduced.
