When the band-shaped packaging material is passed through the bag making machine, it is bent so as to be substantially closed in the width direction, and while sending the bent band-shaped packaging material in the vertical direction or the horizontal direction, both side edges are vertically sealed to form a cylinder. In a vertical or horizontal bag making and filling machine for forming a bag packaging body by forming a cylindrical packaging material, filling the cylindrical packaging material with a package, and transversely sealing the cylindrical packaging material in a transverse direction ,
A thin disc, a pair of pinching rollers disposed on each side of the disc side surface of the disc so as to be movable in the plate thickness direction of the disc in a manner of sandwiching the outer edge portion of the plate side surface between the roller end surfaces, And an urging means for applying a pressing force for pressing the pinching rollers against the disk constitutes a line giving part for applying a line to the packaging material,
The bag forming and filling packaging characterized in that, in the line-feeding portion, a line is provided to the packaging material by sandwiching the packaging material between the outer edge portion of the disc and the roller end surface of the pinching roller. Packaging material creasing device in the machine. The pair of sandwiching rollers are disposed on the same rotational axis parallel to the rotational axis of the disk outside the disk, and the roller end surface of the sandwiching roller and the surface of the outer edge of the disk forms the overlapping portions each other and partially a parallel flat together, bag-making packing according to claim 1, characterized in that it sandwiched the packaging material between the front and back in the overlapping portion Packaging material scoring equipment for packaging machines. According to claim 1 or 2, characterized in that it comprises a releasing means pressing moves the pinch roller in a direction away from the plate side surface of the disc against the pressing force of the biasing member Packaging material scoring equipment for bag making filling and packaging machines. The said packaging material is a strip | belt-shaped packaging material, It is provided with the position adjustment mechanism which makes it possible to adjust the position of the said line | wire provision part to the width direction which cross | intersects the feed direction of the said strip | belt-shaped packaging material. The packaging material creasing apparatus in the bag making filling packaging machine as described in any one of 1-3 . A nozzle that blows hot air for heating on a portion of the wrapping material that is sandwiched between the outer edge portion of the disc and the roller end surface of the sandwiching roller or a middle portion of the packaging member; The packaging material creasing apparatus in the bag making filling and packaging machine according to any one of claims 1 to 4 . It further comprises a heel-stretching roller that applies a pulling force in the width direction to the passing wrapping material to extend the crease generated in the wrapping material downstream of the line-feeding portion in the wrapping material feeding direction. The packaging material creasing apparatus in the bag making filling packaging machine as described in any one of Claims 1-5 . When the band-shaped packaging material is passed through the bag making machine, it is bent so as to be substantially closed in the width direction, and while sending the bent band-shaped packaging material in the vertical direction or the horizontal direction, both side edges are vertically sealed and the cylinder In a vertical or horizontal bag making and filling machine for forming a bag packaging body by forming a cylindrical packaging material, filling the cylindrical packaging material with a package, and transversely sealing the cylindrical packaging material in a transverse direction ,
A thin disc, a pair of pinching rollers disposed on each side of the disc side surface of the disc so as to be movable in the plate thickness direction of the disc in a manner of sandwiching the outer edge portion of the plate side surface between the roller end surfaces, And a streak imparting unit that imparts a streak to the packaging material is configured by a biasing unit that imparts a pressing force that presses the pinching roller against the disk.
The circumferential speed direction of the thin peripheral surface at the contact position of the disc with the packaging material is aligned with the feeding direction of the packaging material, and between the outer edge portion of the disc and the roller end surface of the pinching roller. The packaging material is sandwiched in a direction intersecting the feeding direction by the urging means, and the packaging material is passed through the streaking portion in the sandwiched state, thereby giving a streak to the packaging material.
