度を低下させるだけでなく、膜の過溶融や時には過熱に
よつて合成樹脂膜を燃やす場合がある。In each of the above conventional examples, as a means for guiding the heat of the flame due to the combustion of gas to the synthetic resin film, for example, direct conduction of heat by a heated metal is used, and fuel consumption and time are wasted in the conduction of heat. Not only does the fuel cost increase and the working speed decreases, but there is a case where the synthetic resin film is burned due to overmelting or sometimes overheating of the film.

In order to obtain a hole puncher for synthetic resin film mainly used for multi-farming, which has a high speed and can prevent the occurrence of an accident due to overheating of the heat transfer body by heating the synthetic resin film uniformly to a melting temperature appropriately. To do.

る。<< Means for Solving the Problem >> The present invention provides a burner section 4 for burning gas inside a combustion chamber 3 having a through hole 2 communicating with the outside air, and a heating section of a heat pipe H below the burner 4. 6 is detachably inserted and fixed, and these are surrounded by a casing C to be integrated,
It is characterized in that the other end side of the heat pipe H is led out to the outside of the casing, and the leading end is brought into contact with the synthetic resin film to form a heat radiating portion 8 for melting the same.
《作用》 一般に、金属に伝わる熱の伝導は、銅の場合で0.923cal
・cm-1s-1deg-1（20℃）であり、決して速いものとはい
えない。<Action> Generally, heat conduction to metal is 0.923 cal in the case of copper.

“ヒートパイプ”は作動流体の蒸発／凝縮サイクルによ
つて熱交換するものであり、上述の熱の伝導とは無関係
に加熱され、銅の約200倍の熱伝導率を得られる。On the other hand, the "heat pipe" as the melting medium of the synthetic resin film of the present invention exchanges heat by the evaporation / condensation cycle of the working fluid and is heated independently of the above heat conduction, The thermal conductivity is about 200 times that of copper.

均一になることが少ない反面、過剰に加熱されることは
ない。In this heat pipe method, since the heat radiating portion releases heat by condensing the working gas, its temperature is uniform at the gas / liquid boundary, and the temperature is not uniform due to the difference in distance as in the case of copper conduction. Although it rarely becomes uniform, it is not overheated.
