ルムの融着面を均一に冷却する。 Next, in the second embodiment shown in FIGS. 3 and 4, the case where a single row of seals is performed is taken as an example.
Pressurized air discharge opening 15' provided in the crimp surface 13
are communicated on the crimping surface 13 by providing a V groove 16, and the pressurized air coming out from the discharge opening 15' is connected to the V groove 16.
Due to the presence of the grooves 16, a uniform pressure is applied to the film to peel it off from the pressure bonding surface 13, and the fusion bonding surface of the film is uniformly cooled.
