This is because the original packaging film is cut with a slitter for each required size in each packaging bag, the cut packaging film is formed into a bag shape, and the formed overlapping parts are vertically sealed with a vertical seal bar, and then vertically sealed. The specified position of the cylindrical packaging film is sandwiched between the horizontal seal bars and laterally sealed, and the raw material is introduced into the finished bag-shaped packaging film using a filling pipe, and then the raw material inlet is laterally sealed. Seal with a bar, make a notch notch with the notch cutter device near the end of the sealed horizontal seal part, and cut the cutting cutter device near the center of the sealed horizontal seal part. Use it to separate it and create a stick-type individual packaging bag.

  An example of such a vertical multi-row automatic packaging machine is disclosed in Patent Document 1. As described above, the normal vertical multi-row automatic packaging machine is provided with two types of cutter devices, and this notch cutter device is adapted to the width of the stick type individual packaging bag to be manufactured. The deployment position can be changed.

  Conventionally, there is a roll type automatic packaging machine configured to continuously seal-mold three-way type packaging bags. This is done by folding the original wrapping film in half and forming it into a bag shape. The overlapped part of the formed ends is vertically sealed with a vertical seal roll, and the specified position of the packaging film formed into a cylindrical shape by the vertical seal is horizontally sealed. It is sandwiched between rolls and laterally sealed, and the raw material is introduced into the finished bag-shaped packaging film using a filling pipe, and then the raw material inlet is sealed with a lateral seal roll. A notch cutter is used for the vicinity of the end using a notch cutter device, and the sealing is performed for the vicinity of the center of the sealed side seal portion using the cutting cutter device, resulting in a three-way individual packaging bag. .
