ABSTRACT:
A bag manufacturing and packaging apparatus includes a bag manufacturing unit that tubularly forms a strip film and manufactures a bag filled with articles; a feed roller unit that feeds a strip, to which the bag manufactured by the bag manufacturing unit is mounted; and a mounting unit that mounts the bag to the strip fed by the feed roller unit. The strip is rectilinearly maintained between the feed roller unit and the mounting unit by imparting a bend on the strip in the transverse cross section that intersects a transport pathway of the strip. The object of the present invention is to provide a bag manufacturing and packaging apparatus that, even if the strip to which bags are mounted lacks rigidity, can smoothly feed the strip, automatically thread the strip to the mounting unit, and form appropriate slits in the strip.
