Claims

[Scope of utility model registration request]

A pull-out roller and a discharge roller have the same diameter and are mounted on shafts parallel to each other in the front and back and are driven to rotate in the same direction at approximately the same speed. A pair of left and right slide plates that are reciprocally driven in a direction of installation, and a shaft rotatably mounted between one end of these slide plates and located closer to a film supply section than the pull-out roller, and the film to be drawn out by the pull-out roller. An inlet roller attached to a semicircular circumferential surface, and a shaft having the same diameter as the inlet roller and rotatably mounted between the other end of the slide plate and located closer to the film ejecting section than the ejecting roller. An exit roller that attaches the film from the entrance roller to the semicircular surface and directs it to the discharge roller, and a sealing device and a cutting device that are arranged in parallel on the film travel path between the entrance and exit rollers. A line processing device is provided, and a line connecting the axes of the drawer and discharge rollers is made parallel to a line connecting the axes of the inlet and outlet rollers, and a perpendicular dimension between these two lines is determined by the drawer. , the size is set to be the same as the sum of the radii of both rollers on the entrance side, and at least the reciprocating speed of the slide plate toward the film supply section side is set to 1/2 of the film traveling speed. A continuous bag making device featuring:
