フィルムを一定方向に一定量づつ間欠送りしている。The film feeding device in this type of bag making machine transmits the rotation of the output shaft of the motor to a crank mechanism via a continuously variable speed pulley and a speed reducer, and converts it into a reciprocating rocking motion of a sector gear. . Furthermore, this reciprocating oscillating motion of the sector gear is made into the forward and reverse rotation of the gear, and only one of the forward and reverse rotations of the gear is transmitted to the feed roller by the electromagnetic clutch, and the rotation between the feed roller and the pressure roller is The film sandwiched between the two is intermittently fed by a certain amount in a certain direction.

リに大きなスラスト荷重がかかる。When a large torque fluctuation occurs on the output side of the continuously variable speed pulley, the belt slips with respect to the pulley, and the rotation speed on the output side of the continuously variable speed pulley changes. In order to remove this, if the movable pulley is pressurized in the axial direction with a strong spring force, a force acts on the pulley on the opposite side in the direction of opening, and a large thrust load is applied to the movable pulley.
