Abstract
A bag making and packaging machine has pull-down belt mechanisms, a transverse sealing mechanism, a rotatable folding member, and a gas blowing mechanism. The folding member, before the transverse sealing mechanism, seals a cylindrical film, pushes against a side portion of the cylindrical film to thereby fold the cylindrical film inward and form a fold in the cylindrical film. The gas blowing mechanism blows a gas onto the fold to thereby inhibit the cylindrical film from sticking to the rotating folding member.
