Abstract: An extensible-retractable helically reinforced hose is formed by helically wrapping a freshly extruded bead of thermoplastic material about a rotating mandrel to form a helical array of spaced reinforcing coils, and by helically wrapping a freshly extruded thin yet wide web of thermoplastic material so edge regions of the wide web are placed onto and bond continuously with the peripheries of each adjacent pair of the reinforcing coils, with a leading edge region of each new wrap of the web overlying and bonding to a trailing edge region of a prior web wrap. Central portions of each web wrap extend radially inwardly and are sandwiched between adjacent reinforcing coils when the hose is retracted to a minimal axial length.

Abstract: Helically reinforced, flexible tubing or hose is formed from continuously extruded thermoplastic material helically circumferentially wound at a wrapping station around an array of bearing-supported rods that are concurrently but individually turned and are adjustably canted relative to an imaginary center axis. The tubing or hose being formed has a continuous reinforcing rib helically wound therearound and continuously integrally connected thereto. The resulting tubing or hose may be transversely severed at intervals along its length to provide discrete lengths of hose that are annealed while axially compressed to relieve stress.

Abstract: A method of forming a hose includes: extruding a web of plastics material from a first extruder; helically winding the extruded web about a mandrel or at least one rotating rod to form a wall of the hose; feeding an electrical wire into a second extruder; extruding a bead of plastics material around the electrical wire from the second extruder, wherein the first electrical wire is positioned at a first location within a cross-section of the bead that comprises a bonding surface; cooling the bead to cool the plastics material adjacent the first location to prevent migration of the first electrical wire from the first location; re-heating the first bonding surface to cause the plastics material of the bonding surface to become molten; and helically winding the bead onto the hose to put the bonding surface into contact with, and to cause bonding with, the wall of the hose.
