れぞれ個別に経て製造されている。かかる従来法では、
各工程間で編組スリーブが変形したり屈曲したりすると
いう問題があり、更には、各工程での仕掛り品が増え、
在庫管理が繁雑となり、各工程間の運搬経費が増大する
という問題もある。BACKGROUND ART Conventionally, a braided tube in which a varnish is applied to a braided sleeve and impregnated with the varnish has been individually manufactured by, for example, a braiding process, a rewinding process, a heat cleaning process, a varnishing process, and a diameter adjusting process. In such a conventional method,
There is a problem that the braided sleeve is deformed or bent between each process, and more work in process in each process,
There is also a problem that inventory management becomes complicated and transportation cost between each process increases.
そこで、本出願人は、先にスリーブの編組、ワニス処
理、加熱、硬化処理を連続化することを提案した。この
方法によれば、上記従来法の問題を解消することができ
る。Therefore, the present applicant previously proposed that the braiding of the sleeve, the varnish treatment, the heating, and the curing treatment be continuous. According to this method, the problems of the conventional method can be solved.
しかしながら、上記連続法によって得られた編組チュ
ーブは、ワニスがスリーブの内面にまで浸透してしま
い、後の工程で電線等の挿入体を編組チューブ内に挿入
する作業がやりにくくなるという新たな問題が生じるこ
とがわかった。また、編組チューブ表面のワニスの付着
状態も不均一で、付着斑が生じる。However, the braided tube obtained by the above continuous method has a new problem that the varnish penetrates into the inner surface of the sleeve, which makes it difficult to insert an insert such as an electric wire into the braided tube in a later step. Was found to occur. In addition, the state of varnish adhesion on the surface of the braided tube is also nonuniform, and uneven adhesion occurs.
従って、本発明の目的は、ワニスがスリーブ内面にま
で浸透せず、内面が平滑で、後工程での挿入体の挿入作
業が容易であり、しかも表面のワニス付着状態が均一で
斑のない編組チューブを得ることのできる方法を提供す
ることにある。Therefore, the object of the present invention is that the varnish does not penetrate to the inner surface of the sleeve, the inner surface is smooth, the insertion work of the insert body in the subsequent step is easy, and the varnish adhesion state on the surface is uniform and the braid is uniform. It is to provide a method by which a tube can be obtained.
本発明者等は、上記目的を達成すべく鋭意検討を重ね
た結果、編組スリーブ内に気体を供給しながら連続処理
を施せばよいことを見出し、本発明を完成させるに至っ
た。As a result of intensive studies to achieve the above object, the present inventors have found that continuous treatment may be performed while supplying gas into the braided sleeve, and have completed the present invention.

ブの製造方法である。That is, the present invention, when producing a braided tube by continuously performing sleeve braiding, varnish treatment, heating, and curing treatment, performing varnishing, heating, and curing treatment while supplying gas into the braided sleeve. Is a method for manufacturing a braided tube.
本発明の編組チューブ製造法では、編組スリーブ内に

チューブ内面が平滑になり、後工程での挿入体の挿入作
業が容易になる。また、編組チューブ表面のワニス付着
状態が均一になる理由は、良くわからないがスリーブ内
圧が高くなることと関連があるものと考えられる。In the braided tube manufacturing method of the present invention, since varnish treatment, heating, and curing treatment are performed while supplying gas into the braided sleeve, the pressure inside the sleeve becomes high, and the varnish is prevented from penetrating to the inner surface of the sleeve. It As a result, the inner surface of the braided tube becomes smooth, and the insertion work of the insert body in a later step becomes easy. Further, the reason why the state of varnish adhesion on the surface of the braided tube becomes uniform is thought to be related to the increase of the internal pressure of the sleeve although it is not clear.
