    • PROBLEM TO BE SOLVED: To provide a center sealing apparatus capable of providing a reliable and beautiful sealed state even when a bag-making and filling machine is operated at high speed and also capable of shortening the dropping distance of an object to be packaged and providing a favorable sealed state even in high-speed operation in the case where the apparatus is applied to a vertical type bag-making and filling machine. SOLUTION: The center sealing apparatus 10 has a pair of sealing mechanisms 16, 17, each being disposed on each of both sides across a transfer passage for superposed edges of a cylindrical film, in such a manner that they are movable so as to approach and leave each other. Each of the sealing mechanisms 16, 17 has a belt set 23 stretching a steel belt 22 on a driven pulley 19 and a drive pulley 21 which are spaced from each other in the direction in which the film is transferred. A heater block 24 having the size of a predetermined length in the direction in which the film is transferred is disposed between the driven pulley 19 and the drive pulley 21. The steel belt 22 in a region where the superposed edges f of the film are pinchingly held is heated by the heater block 24 throughout a predetermined length thereof in the direction in which the film is transferred.
