At the same time, the tube film is cut between the objects to be packaged, and each cut end is formed by heat sealing. In this case, the bag 1 as shown in FIG. 7 is formed by forming the mountain-shaped cuts 2 in advance in the strip-shaped film at equal intervals in a column and continuously applying the adhesive tape 3 to the strip-shaped film so as to cover each cut. Can be formed one after another. Therefore, the tape 3 is in close contact with the entire surface of the bag 1 from end to end, and it takes time to peel off the tape end 3a from the bag surface for opening. If, during the manufacturing process, only the end 3a of the tape is peeled off from the surface of the bag 1, the tape 3
It is conceivable that the tape naturally adheres to the bag again due to the pressure-sensitive adhesive, and the end of the tape peeled from the bag sticks to the foreign object, and the tape is flipped off the bag by the movement of the foreign object. It is also possible that

成する。(Means for Solving the Problems) In order to eliminate the above-mentioned drawbacks, the present invention squeezes a band-shaped film F for forming a bag and a tape T having a pressure-sensitive adhesive surface, and holds the film by a rotational movement of both. Main roll opposite to the tape for continuously attaching the tape to the film
12 and a pressing roll 25, and a cut-off roll 14 that forms a chevron-shaped cut 15 in a row at the portion of the strip-shaped film F where the tape T is to be pasted. A plurality of guiding rolls 23 and 24 for forming a meandering trajectory of the tape in front of the press-contact roll 25 and a specific hooking roll 24 among the rolls are periodically moved to loosen the tape. Moving means for forming the tape, a means for pressing a slack portion of the tape from the pressure-sensitive adhesive surface side with a pressing element to bend a part of the tape into a U-shape or a V-shape, and a fold for pressing the bent portion of the tape in two layers. It comprises a forming means and a variable dancer roll 22 which constantly applies tension to the tape with a smaller force than the adhesive force of the fold formed on the tape.

フイルムFの切れ目15の上に貼り付けられる。(Effect) Each time the hooking roll 24 supporting the tape T in a meandering form moves periodically by the movable means, the tape is loosened, and the slack portion of the tape is pushed by the bending means to form a U-shaped or V-shaped tape. In addition, the fold forming means presses the U-shaped portion of the tape and forms two folds A at equal intervals by sticking the pressure-sensitive adhesive surface of the tape. Moreover, the variable dancer roll 22 always acts on the tape with a tension smaller than the adhesive force of the folds. In short, since the variable dancer roll 22 has a buffering action, the tape T is pulled without peeling the folds. Then, it is stuck between the main roll 12 and the press roll 25 on the cut 15 of the strip film F.

る。In FIG. 1, the adhesive tape (T) supported on another shaft (20) is meandered by a dancer roll (22) that can move up and down along a slit (21), and then is idle-low (23) and hooked. By being drawn between the press roll (25) and the main roll (12) via the roll (24), the fifth
As shown in the figure, the adhesive tape (T) is cut at each spot (15)
Is attached to the film (F) so as to cover the film. According to the enlarged FIG. 2, the hanging roll (24) is supported by a movable member (27) that can move up and down around a shaft (26), while being formed by a cam coaxially with the main roll (12). An operation mechanism (28) is provided, and a pin (29) provided on the movable member contacts the cam. The adhesive tape (T) attached to the film is always stretched by pulling the tape, and the tape (T) is loosened every time the pin (29) falls into the hollow (30) of the rotating cam (28). Occurs. A pushing element (50) formed by a nozzle (31) is provided on one side of the adhesive tape, and a chamber (32) is provided on the other side. When the adhesive tape (T) becomes loose,
As shown in FIG. 3, the pressure-sensitive adhesive tape (T) is partially pushed into the chamber (32) by the air pressure blown from the nozzle (31). Moreover, a pleated bar (33) is provided at the pointed end of the movable member (27) as shown in FIG. 4, and the adhesive tape (T) is folded in two by the upward movement of the pleated bar (33). The creased portion is clamped by a large fold (34) at the rim of the chamber and sticks to form a fold. As a result, folds (A) are partially formed on the tape as shown in FIG.

もののようにテープの自然剥離もない。(Effect) In the present invention, the tape is loosened by displacing the hooking roll 24 in a meandering track formed in the middle of the tape transport track.
After folding the slack portion to form a fold, the tape is moved by the buffer of the dancer roll 22 so that the stick of the fold portion does not peel off, and the tape is pasted on the cut 15 of the strip film. The folds of tape formed by such a device protrude from the surface of the bag-forming film.
In other words, the folds are firmly adhered to the film on both sides, so that the folds are caught by foreign objects and do not spontaneously peel off from the film, and the film can be opened only by applying a certain amount of force. Therefore, there is no difficulty in peeling off the tape as in the conventional product in which the entire tape is in close contact with the bag, and there is no spontaneous peeling of the tape as in the case where the end of the tape is intentionally peeled off.
