Claims

[Scope of utility model registration request]

The film is held between a relatively large-diameter heat roll rotated by power transmitted from a drive shaft, and a first auxiliary roll and a second auxiliary roll of relatively small diameter that are in contact with the circumferential surface of the heat roll, In the sealing device that heats and welds the film so that the film flows in the direction from the first auxiliary roll to the second auxiliary roll, an auxiliary heat source block 24 formed of a thermally conductive material is provided as one of the sealing devices. A rotary sealing device for a packaging machine, characterized in that the rotary sealing device for a packaging machine is installed so that one side of the surface is along the heat roll and another part of the surface is along the film in front of the first auxiliary roll.
