PROBLEM TO BE SOLVED: To provide a bag making machine that makes a plastic bag having a spout provided on an end face by a general feed system for shell material when making the plastic bag, has simple constitution, is low-cost and made fast, and can make two plastic bags at each time.SOLUTION: A first shell material 1 has a first folded part formed, a second shell material 2 is punched by hole forming means 14, and a hole is formed in the second shell material 2. Further, a spout is inserted into the hole, and a spout sealing device 17 heat-seals the spout and second shell material 2. Furthermore, the second shell material 2 is guided by a shell material guide mechanism 18 after heat-sealed, and folded to form a second folded part of the second shell material 2, and the spout is inverted by the second folded part. Then the second folded part and a first folded part are heat-sealed around the spout by peripheral sealing devices 20, 24, so that the second folded part and second shell material 2 are heat-sealed. |
