Abstract

See full text

A method of continuously forming an axially extensible and retractable hose comprising: continuously forming an axially extending helix with axially spaced reinforcing coils from extruded thermoplastic material having a uniform cross-section along its length; and continuously bridging between an adjacent pair of the reinforcing coils with a continuous web of extruded thermoplastic material of substantially uniform width and relatively thin cross-section to form a continuous, helically extending sidewall, with the web having one of two opposite edge regions bonded continuously to a relatively flat outer bonding surface of a radially outwardly located portion of one of the adjacent pair of reinforcing coils, with the web having the other of the edge regions bonded continuously to a relatively flat inner bonding surface of a radially inwardly located portion of the other of the pair of reinforcing coils, and with the edge regions continuously radially separated from each other by the helix.
