When the two swing arms 11, 11 swing to the ironing start point shown in FIG. 3A, the swing arms 11, 11 wrap the ironing members 27, 27 projecting forward from the horizontal sealing jaws 21, 21. 3b, and the bar 27b at the tip of the ironing member 27 is held between the horizontal sealing jaws 21 and 2 so that the packaging material s is sandwiched from both sides from this position to the ironing end point shown in FIG.
1 is passed through from the lower side to the upper side, and the internal filling w is scraped down. On the other hand, horizontal seal jaw 2
After reaching the ironing end point with a delay to the ironing members 27, 27, the parts 21 press the packaging material s from the front and back for the first time, and move from this to the seal end point (C). And all the cycles of the lateral sealing operation are completed.

However, this can be replaced with another axis moving means using a cam or an air cylinder. it can. Although the present invention has been described above with reference to an example of a packaging machine that does not use a filling cylinder, it is needless to say that the present invention can be applied to a general packaging machine.

れに所要の熱シール動作を行わせることができる。As described above, according to the present invention, the lateral heat sealing which always faces the heat sealing direction via the planetary gear mechanism is attached to the tip of a pair of revolving arms formed in a U-shaped frame. Since the components are arranged, the swivel arm can be given sufficient strength to withstand the pressure of the horizontal seal, and at the same time, the horizontal heat sealing can be performed regardless of the distance of the horizontal seal. The required heat sealing operation can be performed on the member while maintaining the member in a constant posture in a stable state.
