<P>PROBLEM TO BE SOLVED: To provide a bag-making packaging machine capable of reducing poor sealing caused by a packaged article catching in lateral seal portions. <P>SOLUTION: The bag-making packaging machine is provided with an upper tube 12, a lower tube 13b disposed therebelow, a former 13a, a lateral sealing mechanism 17 below the lower tube 13b, and opening and closing sliding members 18a. A packaged article C is dropped through the interiors of the upper tube 12 and the lower tube 13b. The former 13a winds a sheet film F around the circumference of the lower tube 13b to convert it into a tubular film Fm. The lateral sealing mechanism 17 laterally seals the tubular film Fm. The opening and closing sliding members 18a, which are disposed between the upper tube 12 and the lower tube 13b, shut off an upwardly oriented flow of gas from the interior of the lower tube 13b when in a closed state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
