<p>PROBLEM TO BE SOLVED: To provide a bag making machine where a trunk part, a side gusset part and a fastener part are sequentially continuously produced at a plastic bag.SOLUTION: A first fastener material 5 is applied to a first trunk material 1 and a second fastener material 6 is applied to a second trunk material 2. The first and second fastener materials 5, 6 are inserted between the first and second trunk materials 1, 2 and coincided with each other when the first and second trunk materials 1, 2 are overlapped each other. Further, a third fastener material 7 is applied to a side gusset material 3. The third fastener material 7 is inserted between the first and second fastener materials 5, 6 when the first and second trunk materials 1, 2 are overlapped each other and the first and second fastener materials 5, 6 are coincided with the third fastener material 7.</p> |
