Abstract

PURPOSE:To produce a thermal insulation hose light in wt and having an excellent flexibility, by winding in a spiral soft strips around at an upper and a lower part of a hard reinforcing material, and by filling a gap between the reinforcing material and the strips with gas or a foaming material. CONSTITUTION:Strips 21 and 22 made of soft plastic resin are continuously extruded so that their respective one ends in a transverse direction are welded at an upper and a lower part of an intermediate reinforcing object 1, and their respective other ends project horizontally in a reverse direction to each other. Said extruded object is wound in a spiral around the outer circumference of straight bar rollers 3a-3c rotating in the same direction at the same speed, the one ends of the strips 21 and 22 welded to the reinforcing object 1 and the other projecting ends of subsequent strips 21 and 22 being welded together. Thus, an inner and an outer wall of the strips 21 and 22 are provided at spiral intervals, and gaps 4 are also provided between the two walls. Gas or a foaming material being then blown into an open part 6 from a filling nozzle 6 fills the gaps 4.
