Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. 8-40405, for example, a packaging apparatus is a sheet which can be heat-welded so that a part thereof overlaps a guide of an article to be packaged and a former which also serves as a molding means. Is wound, and the overlapping portion is thermally welded by a sealer to form the sheet into a cylindrical body.
Such a sealer includes a heating unit having a built-in heater and an air cylinder for pressing the heating unit against the former. Since the bonding strength and flatness of the seal portion by such a sealer are greatly affected by the temperature and pressure of the heating means, it is necessary to control the temperature and pressure to reference values.

ある。Although the temperature can be maintained at a constant value with relatively high accuracy, there are various problems because the pressure depends on the air pressure. In other words, if a cylinder with a large output is used to speed up the contacting / separating operation of the sealer, fine pressure adjustment becomes difficult, and if a small air cylinder is used to control the pressure with high accuracy, high-speed driving becomes difficult. In addition to the above, there is a problem that vibration is generated due to the mass of the heating means and the spring effect of the air cylinder, resulting in poor connection. In order to prevent such vibration, it is conceivable to use a damper, but there is a problem that the device becomes complicated. The present invention has been made in view of such a problem, and an object of the present invention is to provide a packaging device capable of pressing a sealer against a former with a constant pressure without lowering exercise performance. is there.
