Title: HELICALLY WOUND FLUID-FLOW HOSE
Abstract:
A fluid supply hose having one or more support ribs, such as a helical support rib that forms a coil and/or individual support rings, of a relatively stiff thermoplastic material, and a thin web or wall of thermoplastic material that extends between the inside, outside or both of the ribs. The hose is exposed to an annealing process comprising: bringing the hose to a fully compressed position where the ribs are brought close together; heating the hose; while the hose is hot, extending the hose axially to a partially extended position where the distance between adjacent winds of the rib or rings of the hose when the hose is in the partially extended position is between about 20%-95% of the distance between adjacent winds of rib 20 or rings 40 of the hose when the hose is in the fully extended position; and allowing the hose to cool in the partially extended position.
