Claims (3)

The wrapping material is fed out from the raw material roll of the wrapping material, the inner surfaces are heat-sealed in a palm-like shape, and the folds extending in the width direction of the wrapping material are formed so as to have an arrangement pitch of the required dimensions, The wrapping material with a pleat is hung on the former, and the package-filling cylinder passed through the inside of the former is bent into a cylindrical shape so that both ends of the packaging material are connected and sealed as a packaging cylinder. It hangs down below the package filling cylinder, and then, at the position below the package filling cylinder, the two strips of heat sealing are applied to the position away from the crease of the packaging cylinder and between the two strips of heat sealing. A vertical pillow packaging body having a self-supporting property in which the folds are hung down to the substantially peripheral edge of the bottom surface portion and the folds concealed the bottom surface portion by inserting a cut of the bag separation and turning the separated package upside down. Manufacture Method of manufacturing a pleated vertical pillow packaging characterized and. An original roll in which creases extending in the width direction of the wrapping material are formed so as to have an arrangement pitch of the required dimensions by winding the inner surfaces of the wrapping material in a palm-shaped heat-sealed manner The packaging material with a pleat is drawn out from the former, hung on the former, bent into a cylindrical shape so as to wind the packaging-filled cylinder passed through the inside of the former, and the packaging material is connected and sealed at both ends of the packaging material. As shown below, the two parts are heat-sealed by two heat sealers at a position away from the crease of the packaging cylinder below the filling cylinder. A vertical pillow having a self-supporting state in which the folds are hung down to the substantially peripheral edge of the bottom surface portion and the folds concealed the bottom surface portion by inserting a cut of the bag between them and turning the separated package upside down. Packaging Method of manufacturing a pleated vertical pillow packaging, characterized in that to produce the. The upstream and downstream slit forming plates are in close contact with the outer surface of the packaging material, and the packaging material is fixed by the downstream slit forming plate and the corresponding packaging material presser plate when the packaging material is stopped intermittently. The fold folding plate is pushed into the gap between the upstream and downstream slit forming plates, and the upstream side of the packaging material is pulled to perform the fold folding, and then the upstream slit forming plate and the corresponding packaging material pressing plate. And fixing the upstream side of the fold folding of the packaging material, and then retracting and returning the fold folding plate, and then a pair of crease heat sealers provided corresponding to the upstream and downstream slit forming plates To close the fold-folded portion, and then apply a heat-sealing to the fold-folded portion, and then open a pair of crease-sealing heat sealers, and upstream and downstream packaging presser plates The retracted return, then, the production method of and performing the next intermittent travel of the packaging material [Claim 1] or pleated vertical pillow packaging body according to [claim 2].
