る。(Prior arts and problems to be solved by the invention) While pulling out a rolled vinyl sheet tube or the like, a vinyl bag is formed by forming a vinyl bag while forming a bottom portion by electrothermal bonding or the like at regular intervals. In a form in which the product can be loaded into the bag by inflating it with a bag or the like, it is difficult to open the bag mouth of the vinyl bag, hold it, and the like, and it tends to be complicated. Therefore, the present invention forms a bag bottom by temporarily inflating it while pulling out a sheet cylinder in a rolled state or the like, and facilitates continuous open bag making.

る。(Means for Solving the Problem) In the present invention, the sheet cylinder 1 is extended inside the drawer portion of a series of sheet cylinders 1 that are in communication with each other on the drawer side of the expansion cylinder body 15 that extends the seat cylinder 1. The sheet cylinder 1 is maintained in a fixed position by interposing the tube-expanding body 2 having an opening-expanding plate 19 and an opening-and-expanding piece 22 that expands and expands in the front-rear direction and the wide left-right direction. While being drawn out while being guided by the tube-expansion guiding device 3, the sheet cylinders 1 that are polymerized along the expansion direction by the opening / spreading piece 22 are joined together on the extraction side of the tube-expansion body 2 to form the bag bottom 4. The packaging bag manufacturing apparatus is characterized in that the packaging bag 5 is obtained.

る。(Operation and Effect of the Invention) One end of a series of sheet cylinders 1 in a rolled state or the like is pulled out to the expansion guide device 3, and inside the sheet cylinder 1,
An expansion cylinder body 2 having an expansion plate 19 and an expansion piece 22 for expanding and expanding the seat cylinder 1 in the front and rear and in the wide left and right directions is inserted on the side of the expansion cylinder body 15 on which the seat cylinder 1 is drawn out. Then, the open end of the sheet cylinder 1 with the expanded cylinder body 2 inserted therein is held and pulled out. At this time, the expanded cylinder body 2 is always in a state where the sheet cylinder 1 is expanded and inflated, and is maintained in a fixed position by the expansion cylinder guide device 3, and only the inflated sheet cylinder 1 is pulled out. When the sheet cylinder 1 is pulled out to a predetermined length, it resists the expansion tension by the expansion plate 19 of the expansion body 2 and is partially polymerized along the expansion direction by the expansion piece 22 for electrothermal bonding. The bag bottom 4 is formed by joining by a method or the like.
このときの袋口部は、挾持装置になどによって挾持した

できる。In this way, on the pull-out side of the sheet tube 1 of the tube-expanding body 15 that expands the sheet tube 1 into a long series of sheet tubes 1, the sheet tube 1 is opened and expanded to the front and back and the wide left and right to expand the tube. 1
9 and the expanding / expanding piece 22 are inserted, the expanding cylinder 2 is guided by the expanding guide device 3, and only the sheet cylinder 1 is expanded while maintaining the fixed position. Since the subsequent bag bottom 4 can be pulled out by means of the open / close piece 22, it is possible to accurately and easily carry out the joining of the overlapping portion along the direction of expansion and the sandwiching of the bag mouth portion with high speed. 5 can be formed.
