ABSTRACT:
It is an object of the present invention to manufacture efficiently packing bags which are packed in cases of corrugated fiberboard or the like at a good filling rate without dead space. A film sheet 14 from a bobbin 13 is formed to a quadrangular barrel body 24' along the outside of a cylinder 21 through a former 20, a top plane 10 is squeezed and sealed in a onesidedly slant manner, and then the quadrangular packing bag thus manufactured is transferred, through a guide chute 55, on a belt conveyor 54 in the regular posture (a) or inverse posture (b) to a case of corrugated fiberboard or the like. Conventional packing bag manufacturing mechanisms can be used, packing bags can be mass-produced fully automatically in a uniform manner at a high accuracy, and packing bags thus manufactured can be packed in cases of corrugated fiberboard or the like without dead space, thus reducing costs of transport securely.
