がある。<Prior art> Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 55-29453, a packaging film feeding mechanism of this type of bag-filling-sealing machine has a large number of threads extending along the entire longitudinal length of each film feeding belt. Holes are drilled through the holes at regular intervals, vacuum frames are formed on the back side of the press-contact sections of each belt, and a suction pump mechanism connected to these vacuum frames is operated to cause the packaging film to pass through the holes. There is a type of packaging film that is attracted to the outer surface of each belt and is integrated with the belt to feed out the packaging film.
