    • An improved flexible hose for carrying fluids is disclosed. The hose has a first end and a second end, and is typically in a retracted position when no tensile force placed on an end of the hose and in an extended condition when a tensile force of a pulling nature is placed on an end of the hose. The hose has a thermoplastic cover on its outer surface. The thermoplastic cover has an interior surface and an exterior surface. On the interior surface there is a helical member adhered thereto this helical member being comprised of a material capable of carrying a current of electricity. The hose of the present invention stretches at least 100 percent over its at rest position when a pulling force is placed on one end of the hose.
    • 公开了用于承载流体的改进的柔性软管。 软管具有第一端和第二端,并且当拉伸性拉伸力放置在软管的端部上时,通常处于缩回位置,当拉力不受拉力的作用时,拉伸力不会放置在软管的端部上 。 软管在其外表面上具有热塑性盖。 热塑性盖具有内表面和外表面。 在内表面上有螺旋构件,该螺旋构件由能够承载电流的材料构成。 当在软管的一端放置拉力时,本发明的软管在其静止位置上延伸至少100%。

    • A producing method of a hose including, using a mold assembly constituted by a pair of semicylindrical molds each having a large number of intrusion grooves formed along the axial direction in the cylindrical surface of each of the semicylindrical molds substantially at regular intervals and supplying electrically conductive wire into the hose molding mold assembly substantially linearly along the axial direction of the mold assembly; extruding a molten resin tubularly to supply the molten resin into the mold assembly after the supply of the electrically conductive wire; supplying high-pressure air into the inside of the thus extruded molten resin tube to thereby expand the molten resin tube along the corrugated surface of the mold assembly to bring the molten resin tube into contact with the corrugated surface of the mold assembly and, at the same time, making a part of the tube go around to the outer circumferential surface side of the electrically conductive wire along the intrusion grooves of the mold assembly to thereby enclose the outer circumferential side of the electrically conductive wire; cooling the molded resin tube to retain the shape of the tube; and opening the mold assembly so that a hose body integrated with the electrically conductive wire is taken out from the mold assembly.
    • 一种软管的制造方法,其特征在于,使用由一对半圆柱形模具构成的模具组件,所述模具组件基本上以规则的间隔在所述半圆柱形模具的圆柱形表面中沿着轴向形成有大量的侵入槽,并且提供导电 沿着模具组件的轴向大致线性地进入软管模制组件; 在供应导电丝之后,将熔融树脂管状地挤出以将熔融树脂供应到模具组件中; 向挤出的熔融树脂管的内部供应高压空气,从而沿着模具组件的波纹表面膨胀熔融树脂管,使熔融树脂管与模具组件的波纹表面接触,并且在 同时,使管的一部分沿着模具组件的侵入槽前进到导电线的外周面侧,从而包围导电线的外周侧; 冷却模制树脂管以保持管的形状; 并打开模具组件,使得与导电线集成的软管体从模具组件中取出。
