By the way, in recent years, a landscape, a person, or various patterns may be printed on a paper bag in order to enhance the decorativeness of the paper bag. When printing on the paper bag, the paper bag is folded. The bag paper 1 is printed before the bag paper 1 is folded. A sheet-fed printing machine is mainly used for printing on the bag paper 1, but there is a limit to the body width size of a general sheet-fed printing machine. Naturally, the width W of the printable bag paper 1 is the body width. Within the maximum width of size. However, in the conventional method of folding the bag paper 1 into two to form the paper tube 3, the width of the paper bag including the folding portion 2 is at least twice as large as the bag width. If the bag width of the paper tube 3 is a standard size, it is within the range of the body width size of a general sheet-fed printing machine, and printing on the bag paper 1 is not hindered. There are some large-sized paper bags whose width exceeds 500 mm. As described above, in the large-sized paper bag, the width W of the bag paper 1 is 1200 mm or more in the method of folding the paper cylinder 3 in two and the maximum width (1200 mm) of the body width size of a general sheet-fed printing press is obtained.
Will exceed. Therefore, it is impossible to print the bag paper 1 by a general sheet-fed printing machine, and a custom-made sheet-fed printing machine having a large body width size is required to print a large-sized paper bag. It is virtually impossible to use a printing machine, and even if a custom-made sheet-fed printing machine is used, the manufacturing cost will be extremely high. I had to rely on.

Then, as shown in FIG. 11B, a substantially Z-shaped folded portion 2B is formed. The folding portion 2B folded in this way is guided into the third folding guide body 52 which is arranged so as to face the front side in the rotational feed direction of the second and third sandwiching rollers 53B and 53C. The 3-fold guide 52 is attached to the bag paper 1A by the cam 57A,
In synchronism with the sheet feeding of 1B, the sheet moves in parallel to the side of the fourth sandwiching roller 53D and stops at a position in close contact with the fourth sandwiching roller 53D. Simultaneously with this, the paper pressing roller 66 descends by the cam 58B and sandwiches the bag papers 1A and 1B, and the third nipping roller.
Hit 53C. For this reason, the looseness of the bag papers 1A and 1B caused by the paper feed is caused by the third and fourth nipping rollers 53.
C and 53D, the third and fourth nipping rollers 53C and 53D rotate to feed the bag sheets 1A and 1B downward while biting the looseness of the bag sheets 1A and 1B.
As shown in FIG. 11 (C), a substantially M-shaped folding section 2 is formed on one side of the bag sheets 1A and 1B. In the folding operation of the bag sheets 1A and 1B, the bag sheet 1A is first folded by the folding machine 11A, and after a predetermined time elapses, the bag sheet 1B is folded by the folding machine 11B.
