There is no limitation on the shape of the rod-shaped body, but any shape may be used as long as it is narrow and flat and has sufficient strength to spread the gusset bag. It is preferable that the two rods are paired, and the length from the outer end to the outer end of the pair of rods is equal to the width of the inner surface of the front material of the gusset bag. According to the size of the bag to be spread, two rods are set at an appropriate interval in advance. When inserting,

As a result, the gusset bag has a shape close to a rectangular parallelepiped and forms the bag bottom 7. That is, if the corners of the bag bottom 7 in FIG. 1 are sequentially referred to as a, b, c, and d, xa, x
The lengths of −b, x−c, and x−d are all １ ／ of the gusset width. As a result of sufficiently expanding the gusset material, a gusset material rod 6
A gusset crossing line 8 is formed at the tip end where is inserted. The lower part of the gusset crossing line 8 is folded into a triangle until the upper end x of the bag bottom fused part 4 is formed to form a lower folded part 9. The bag bottom 7 includes a portion surrounded by points a, b, c, and d, a bag bottom fusion portion 4 and a lower folding portion 9.

2 The point on the top is defined as y, and the width of the gusset is 1
The point on / 2 is defined as y ′. While pulling up the rod 6, the tip of the folding plate 10 having the tip shape of the triangle bcy or the triangle ady ′ (not shown in the drawing) is brought into contact with the point y and pressed against the bag bottom 7 to form the upper folded portion 11. . In this step, the gusset bag is folded into a shape as shown in FIG. By using the rod-shaped body 6 and the folding plate 10, the insides of the lower folding portion 9 and the upper folding portion 11 can be folded to the back accurately and finely.

FIG. 9 is an explanatory diagram showing a manufacturing process of the gusset bag shown in FIG. In the following description, the vertical fusion part is a part fused in the film supply direction, and the horizontal fusion part is a part fused in a direction crossing the film supply direction. It has nothing to do with the length and width ratio of the manufactured bags.

I do. When supplying the gusset film 18, the gusset film 18 is folded flat. At this time, as shown in FIG. 9, the proximity part 20 needs to be located at the center part folded flat. The gusset film 18 is ideally in a state where both ends are in contact with each other. However, in some cases, the gusset film 18 may be slightly separated or may be close to the gusset film, and may be folded if slightly. In FIG. 9, the proximity portion 20 is illustrated with a gap provided for the sake of explanation.

に行うこともできる。In the vertical fusion, when X bags are manufactured at once, the width of the film for the front material 1 and the film for the back material 2 is (width of the front portion of the bag × X). X + 1 heated fusing bars are provided, and the bar for fusing at both ends has a half width of the other bars, and is provided at both ends of the film for front material 1. The remaining X-1 bars are arranged at equal intervals inside the bars at both ends. The X + 1 bars are integrally attached, and as shown in FIG. 9, the film is supplied while sandwiching the gusset film between the front material 1 film and the back material 2 film, and Perform fusion. Thereafter, the central portion of the central vertical fusion-bonded portion 24, that is, the vertical cutting line 21, is formed at a stroke by using X-1 cutters arranged at intervals of [(gusset folding depth × 2) + constant intervals]. Disconnect. In some cases, vertical fusion and vertical cutting can be performed simultaneously.

ことができる。Even after the cutting, the horizontal fusing is performed at constant intervals, that is, at intervals of the depth of the product bag, while feeding the bag material at a constant speed without breaking the line. Using a pair of heat bars, horizontal fusion is performed on all X bags at a time. Reference numeral 4 denotes a bag bottom fusion portion. Finally, when cutting is performed at once at the horizontal cutting line 25, X bags are manufactured at once. The horizontal cutting line 25 must not be in contact with the bag bottom fused portion 4 and is preferably close to the bag bottom fused portion 4 within a range where the horizontal cut line 25 is not securely contacted. The positional relationship between the bag bottom fusion part 4 and the horizontal cutting line 25 may be either before or after the film feeding direction as long as the bag bottom fusion part 4 does not contact the bag bottom fusion part 4. In addition, by incorporating a cutting blade into the heat bar for horizontal welding, it is possible to simultaneously perform bag bottom fusion and horizontal cutting.

In the gusset bag thus obtained, since the front material 1 or the back material 2 and the gusset material 3 are actually fused together, no gap as shown in FIG. 8 is left, but in FIG.

As the backing material 2, a film in which an oil-absorbing and heat-fusible polyethylene nonwoven fabric sheet was laminated on the back surface of the same film as the gusset film was used. Printing was applied only to Table Material 1.

It was supplied to a bag making machine having a roll. The distance between the center lines of the heat fusing bars was 100 mm, the fusing width was 5 mm for the end gusset film 17, and 10 mm for the gusset film 18. After completion of the vertical fusion, the film layer was sent to a slitter row, and the film layer was cut into four rows by three slitters arranged at 100 mm intervals. Further, they were sent to a pair of horizontal fusion welding bars, intermittently horizontally fused, and then cut immediately thereafter, and four bags were manufactured for each one of the cuts.
