き出すことにより治具外に取り出される。 Since the present invention is configured as described above, insert either the male or female chuck claw 22 into the guide groove 6 from the end on the first opening member 10 side indicated by the arrow A in FIG. The guide member 5 is pulled along the guide groove 6 in the longitudinal direction. At this time, the welding pieces 23 that are in contact are vertically separated from each other on the receiving surface 3. Next, the separated welding pieces 23 pass through the second opening member 12. When passing through the second opening member 12, the lower welding piece 23 passes between the receiving surface 3 and the holding surface 14, and moves onto the receiving surface 3 in a pressed state. Further, the upper welding piece 23 is guided by the guide surface 13 having an inclined angle, and moves in a state in which it is largely opened upward. Immediately after passing through the second open piece member 12, a bag 24 is placed between the welded pieces 23 which have a large opening.
Insert the opening edge of the bag (or the edge of the bag fabric) and move it in the direction of travel of the chuck.
After inserting the opening edge of the bag body 24, the second opening member 1
2, one of the welded pieces 2 opens upward.
3 falls upwards on the receiving surface 3 due to its own elastic restoration, and becomes in a state where it pinches the opening edge of the bag on the other welded piece 23. In this state, a known heat seal bar (not shown) or the like is moved downward from above the receiving surface 3 to weld the welding piece 23 while sandwiching the opening edge of the bag. After this welding, it is taken out of the jig by pulling it out in the direction of arrow B in FIG.
