Abstract

PURPOSE:To obtain easily a hose with high strength and elasticity by a method in which while plastic is extruded into a double tubular shape concentrically, its outer extruded tube is cut at its extruded front end by an edge being rotating in circumferential direction, simultaneously, the cut parts of the tube are wound and sticked onto the outer surface of an inner extruded tube spirally. CONSTITUTION:While plastic material is extruded into a double tubular shape, its outer extruded tube C to be applied to reinforcing element, is cut at its extruded front end 8 by an edge 5 being rotating in circumferential direction, and simultaneously the cut parts are wound and sticked onto the outer surface of the inner extruded tube D.
