PROBLEM TO BE SOLVED: To enable a stable chuck mounting in producing a bag body with chuck.SOLUTION: The present apparatus: uses both sides of strip-shape sheets as both side parts of the bag body to be formed; moves the chuck in a direction crossing the moving direction of sheet with a drive while pinching the chuck between first and second nippers by using a chuck moving member of chuck insertion part 2; arranges the chuck between both sheets so as to cross the sheets; fixes a pressing member that is a linear spring material to one nipper by a base end side, extends it from one nipper towards the other nipper and fixes it aslant to the moving direction of the chuck with a tip end side so as to be closer to a chuck supply side than the base end side; arranges respective pressing members of both nippers in mutually different positions regarding the moving direction of the chuck; and is capable of moving both nippers towards the chuck supply side leaving the chuck to the sheet by allowing both nippers of chuck to move to the sheet side while inhibiting the chuck from retreating to the chuck supply side. |
