Abstract
A form-fill-seal machine is capable of reducing poor sealing caused by a packaged article catching in lateral seal portions. The form-fill-seal machine is provided with an upper tube, a lower tube disposed therebelow, a former, a lateral sealing mechanism below the lower tube, and opening and closing sliding members. A packaged article is dropped through the interiors of the upper tube and the lower tube. The former winds a sheet of a film F around the circumference of the lower tube to convert same into a tubular film. The lateral sealing mechanism laterally seals the tubular film. The opening and closing sliding members, which are disposed between the upper tube and the lower tube, shut off an upwardly oriented flow of gas from the interior of the lower tube when in a closed state.
