Film rolls at the delivery position and the standby position are supported by supporting units. The roll is passed from the standby position to the delivery position by means of the conveying member provided in the roll conveying unit. As a result, it is not necessary to support the rolls at the individual positions by use of the roll conveying unit, thus permitting simplification of the configuration of the unit. The conveying member has a configuration in which the same is attached to a conveying chain put around the sprockets to make it possible to achieve circumferential travel of the conveying member by a single driving motor. When delivering by connecting to the film from the delivery position, the leading end easily comes off the holding unit by inserting the folded leading end of the film from the standby position and holding the same there.

Film connecting/feeding apparatus

A sealing apparatus applied to a vertical type flexible package forming, filling and closing machine includes a heater block arranged near a filling tube and having a heating ridge, and a web guide attached to the outer surface of the filling tube and having a pair of guide rails, and the heating ridge cooperates with the pair of guide rails to hold the joint of a traveling package web therebetween in such a manner that the joint is elastically deformed in convex form in cross section, whereby the joint is concentratedly applied with heat and thus is heat-sealed.
