<p><P>PROBLEM TO BE SOLVED: To easily manufacture a bag. <P>SOLUTION: In this method for manufacturing a bag, a strip-like film 2a is fed from a web; the film 2a is cut along the feeding direction to be divided into two or more films 2b; and a bag is manufactured using the divided films 2b. The plurality of divided films 2b are jointed to one another to manufacture the bag. A bag body 16 is formed by folding back one film 2b<SB POS="POST">1</SB>after the division, and a flap part 17 or a header part 45 of the bag is formed by superposing and jointing another film 2b<SB POS="POST">2</SB>after the division on/to the bag body 16. The one film 2b<SB POS="POST">1</SB>and the other film 2b<SB POS="POST">2</SB>after the division are fed in synchronization with each other, and both the films 2b<SB POS="POST">1</SB>, 2b<SB POS="POST">2</SB>fed in synchronization with each other are superposed on each other. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
