ことを特徴とする袋折り装置。 A plate-shaped folding member is arranged approximately parallel to the bag material conveyance surface during the conveyance of the bag material formed in a sheet shape, and the center portion of the front edge of the plate-shaped folding member is formed approximately at right angles to the bag material conveyance direction. At the same time, both ends of the front edge of the plate-shaped folding member are formed into inclined edges having the same receding angle, and the bag material folding side of the plate-shaped folding member has a folding side of the center part of the front edge of the plate-shaped folding member. Immediately after, a bottom folding member formed of a plate substantially perpendicular to the plate-shaped folding member is erected along the center line in the conveying direction of the bag material, and folding members are attached to both sides of the bottom folding member. , an end of the same folding member located on the opposite side of the plate-shaped folding member side end of the folding member on the plate-shaped folding member side is arranged close to the bottom folding member,
Furthermore, the bag folding device is characterized in that a plurality of pressing rollers for pinching and pressing the bag material are arranged in parallel on the downstream side of the folding member in the bag material conveyance direction.
