Abstract
A vertical bag-making/filling machine (1) comprises: a film-feeding unit (8) which intermittently feeds a film (F) formed into a tubular shape downward; a nozzle (10) supplying contents (X) into the film; a sealing-off unit (17) arranged below a lower end of the nozzle and forming a bag body (Fg) by heat-sealing the film in a transverse direction; a lower shaping unit (30) regulating swelling of the film on the lower side of the sealing-off unit; an upper shaping unit (40) regulating the swelling of the film on the upper side of the sealing-off unit; and a separating unit (25) for separating the bag body (G) fully filled with the contents by cutting the transverse seal (Y1, Y2) formed by the sealing-off unit.
