Tetrahedral shape extraction bag filling and packaging machine 70 for producing the infusion bag 6 of the vertical sealing device 75 which forms a seat 5 for extraction bag to the tubular body, the sheet feeding means, the cylindrical body of the extraction bag sheet, transverse sealing device 76, and of the first lateral seal forming a second form alternately first transverse seal and the second transverse seal by ultrasonic welding fusing alternately in a direction crossing each other when viewed while repeating the formation of transverse seals alternately have a filling device 80 for filling contents into the interior of the cylindrical body of the extraction bag sheet. Transverse sealing device 76 is provided with a traveling sealing head 76a and a columnar anvil 76b and anvil fixing means 76c. Columnar anvil 76b is rotatable in the circumferential direction, the circumferential surface, having a plurality of flat surfaces 76b1 extending in the longitudinal direction. Transverse sealing is performed and the flat surface 76b1 and the sealing head 76a are opposed. This reduces wear of the anvil 76 b, to facilitate replacement of the wear surface.
