た。(Problem to be solved by the invention) However, in all of the above conventional devices, one blade is attached to a rotary blade mount attached to a rotating shaft, and the cutting edge of the rotary blade is fixed by rotation of the rotary blade mount. Since an opening notch was provided on the side edge seal of the sealed bag that is continuously transferred when passing through the cutting edge passage groove provided on the cutting edge surface of the tip of the blade, for example, the required number of opening notches were provided on the side edge seal of one unit of sealed bag. When providing a notch for opening the bag, it is necessary to either slow down the transfer speed of the sealed bag or speed up the rotation speed of the rotary blade. In some cases, not only does the structure become complicated, but increasing the rotational speed of the rotary blade more than necessary increases the risk and is not easy to implement.
