While being pressed by the pressure roller 69, the plastic film 24 is tightly pressed against the ribbon cylinder 71 and pulled out from the ribbon cylinder body 71.As a result, the pulled out plastic film 24 has a thin strip with "Tsuzume Item" printed on it. The ribbon 72 is covered tightly, and the plastic film 2
4, when the article T is wrapped as shown in FIG. 1, the words "Tsubume Item" will be displayed on the surface of the article. Thereafter, when the article T is lowered with the plastic film 24 stretched, the film holding section 30 rotates from the cutting standby position to the cutting position.

Then, the cutting part 33 protrudes relatively from the opening part 34, and the plastic film 24 located in the opening part 34 is melted and cut together with the thin ribbon 72 by the heat. Then, the entire article T is wrapped with the plastic film 24, and when the plastic film 24 contacts the sealing portion 35, that portion melts and the article T is completely wrapped. In this case, as shown in Fig. 4, the packaged article T has a small ribbon 72 wrapped around the contents of the article T, in this case "sparrow items", so it does not have a conventional label. Does not require stones.

Thereafter, the plastic film 24 is pulled out one after another to wrap a new article, and the plastic film 24 is
; 7J The analysis section 33 separates each item, and the sealing section 35 seals the products, so that the articles are sequentially packaged.

Now, in the case of the 14-piece film, the film cylinder 22 is rotatably supported by the first support mechanism 7, and the ribbon cylinder 71 is rotatably supported by the second support mechanism +Mff 40, and Since the plastic film 24 is pulled out by the pressure roller 69 with the thin ribbon 72 printed with the words "Tsubume Item" tightly packed together, it is no longer necessary to apply a label after the packaging process as in the conventional configuration. Unlike the case where packaging work is required, so-called labeling can be done at the same time as packaging work, thus making conventional labeling unnecessary and greatly improving work efficiency on the user's side. I can do it.

In particular, in this embodiment, the thin ribbon 72 is made of a plastic film, and the film cylinder 22 is
Since the plastic film 24 is made to have a dark blue color, there is no need to apply a blight agent or the like to the thin ribbon 72, and the efficiency of the packaging operation is further improved.
