[Detailed Description of the Invention] [Industrial Application Field] This invention is a method for unwinding a plastic film strip (including a flat tube) wound into a roller shape, printing on it, or packaging using this film strip. The present invention relates to an apparatus for unraveling the roll-shaped film strip in advance and storing VC in a zig-zag manner in a suitable box as a pretreatment when manufacturing bags from the film strip.

[Prior art]

Conventionally, as a method and device of this type, a device as shown in Fig. 3 is known, in which a film (tf There is a method and a device for collecting film between the plates 2 and 3, and when this amount increases to a certain extent, the film strip is folded in a zigzag pattern and is dropped intermittently.

However, in this known method and apparatus, when the film strip F is folded in a zigzag manner between the pair of guide plates 2.3, the thickness of the film strip F becomes extremely thin (3.
0 μ or less), or when the feed speed of the film strip F is approximately 100 yn 7 m or more, especially K 200 m/si
When the film is fed out at a high speed of n or higher, the film strip F rises along one guide plate, and as it descends, the air below causes the film strip F to glide in the width direction and collapse, causing the film strip F to twist. The film passes between the pair of guide plates 2.3 in a straight line from the pair of clamping type conveyor 10 without wrinkles or accumulation in the RC zigzag between the pair of guide plates 2.3. Then, the lower receiving box 24
There are 24 times in the receiving box.
'Q: The rejected film strip is wrinkled, has poor filling efficiency, and has a large number of receiving boxes 24K)I'
When the d-order film sheet F is opened and stored, the length unevenness of the film strips between each receiving box is large, and the film strips F stored in this receiving box 24 are sequentially supplied and processed. For example, when bag making, packaging, etc. are carried out sequentially, the time intervals for supplying the receiving boxes become uneven, making it difficult to manage the work.

Therefore, in order to improve the filling efficiency in the receiving box 24, in the conventional technology shown in FIG. The work is affected by the degree of comfort of the worker, and if the film strip F is pressed too hard, there is a risk that the film strip F will crease or get scratches on the surface.
