VERTICAL FILLING/PACKING MACHINE

摘要

A vertical filling/packing machine comprises a film feed roller (6) for feeding a tubular film (20) vertically downward, a folding device for folding the opposite sides of the tubular film (20) fed by the film feed roller (6) inwardly of the tubular film (20), a pair of squeeze rollers (7) for forming an empty filling portion (20b) in the tubular film (20) by rotating while sandwiching the tubular film (20) filled with contents to feed the tubular film (20) downward, and a unit (8) for heat sealing the tubular film (20). The folding device has a folding guide (2) provided with clearances formed at portions corresponding to the opposite sides of the tubular film (20) and supporting the outside of the tubular film (20), and a pair of folding plates (5) which can advance/retract into/from the folding guide (2) through the clearances formed in the folding guide (2).
