ABSTRACT:
An object of the present invention is to provide a filling apparatus capable of reliably correcting the position of an overlap portion. The filling apparatus includes a forming ring including a plurality of forming rollers and disposed at a predetermined position along the traveling direction of a packaging material (11) in order to deform the packaging material (11) from a web-like shape to a tubular shape, and a longitudinal sealing device (41) for longitudinally sealing opposite side edges of the tubular packaging material (11). One of the forming rollers includes a flange (71or84) which is moved axially by means of a moving mechanism section (72). In this case, even when, within the forming ring, a side edge portion of the packaging material (11) of a certain size impinges on the flange (71or84), the flange (71or84) is caused to move accordingly to thereby avoid interfering with correction on the position of the overlap portion (LP). Therefore, the position of the overlap portion (LP) can be reliably corrected.
