摘要
A vertical type forming, filling and sealing machine according to the present invention includes a film shaping mechanism for forming long lengths of film into tubular shapes, a vertical sealing mechanism (10) for heat sealing the edges of the film formed by the film shaping mechanism in the longitudinal direction of the film to form tubular film, a supply nozzle (3) for supplying contents into the tubular film, and two horizontal sealing mechanisms for heat sealing the tubular film in its width direction. A first horizontal sealing mechanism (20) heat seals opposing inner surfaces of the tubular film except for a portion in the width direction. A second horizontal (30) sealing mechanism is placed below the first horizontal sealing mechanism and heat seals the area which is not heat sealed by the first horizontal sealing mechanism. IMAGE
