けて試験して見た。Therefore, the inventor of the present invention came up with the idea that it would be possible to repair tears, holes, etc. in worn-out seats and hoods using the high-frequency welding machine (high-frequency welder) used to manufacture new seats and hoods. High frequency welding method Sea 1~・
(There has never been an example of this being applied to repairing a hood), and a large electrode mold newly made specifically for repair was attached to an existing high-frequency welding machine and tested.

スパーク要因となる微細な鉄粉等が付着しているためで
あり、このスパーク要因となる鉄粉等を完全に除去すれ
ば、スパークの発生を防止することができる。However, although high-frequency welding can be used to produce new seats and hoods without any problems, when trying to repair tears or holes in worn-out seats or hoods, the seat or hood base fabric A problem occurred in that sparks were generated due to high frequency voltage between the electrode mold and the repair base fabric, resulting in holes in the repair base fabric. The cause of this is that used seats and hood fabrics have fine iron powder, etc. that causes sparks attached to them.If these iron powders that cause sparks, etc. are completely removed, the generation of sparks can be prevented. It can be prevented.
しかしながら、使い古しのシート、幌基布にこびりつい

布目に入込んだ鉄＠等は全く詠ムすることができない。However, it is difficult to completely remove fine iron powder stuck to the used sheet or hood base fabric, especially if the base fabric is waterproof. Iron powder that has gotten into the m or iron that has gotten into the grain of the cloth cannot be chanted at all.
そこで、前記鉄粉の除去を行なわなくてもスパークの発
生しない方法はないものかと考え、スパークの発生原因
を次のような実験で追究してみた。Therefore, we wondered if there was a way to prevent the generation of sparks without removing the iron powder, and conducted the following experiment to investigate the cause of spark generation.

クは発生しないことが判明した。In this experiment, iron chips were sprinkled on a new base fabric, and a repair test piece large enough to cover the repaired area of the base fabric was placed on top of it to investigate how sparks were generated. According to this experiment, if iron powder was shining directly on the peripheral edge of the electrode mold, or if iron powder was present near the inside and outside of the mold edge, sparks were generated from the mold edge. It was found that no spark was generated in the area covered with the repair test piece (which is an electrical insulator) even if there was iron powder underneath the repair test piece.
