摘要: A method of forming a flexible, stretchable, crush resistant axially extending hose includes: providing coils entirely of thermoplastic material to form a continuous and hollow helix; providing a thin, narrow, elongate web of thermoplastic material that extends between adjacent coils of the helix and has edge regions welded to adjacent ones of the coils to form a single continuous wall with the web having a centrally located fold situated between adjacent ones of the coils; and subjecting the hose to an annealing process while axially compressing the hose so that molecules of the thermoplastic material forming the coils of the helix and the thin elongate web are relaxed such that stress is substantially absent from the hose when the coils of the helix are close together.

摘要: A method includes: extruding a continuous web of plastics material from an extruder of a hose making apparatus; helically winding the extruded web about a mandrel or at least one rotating rod of the hose making apparatus to form a wall of the hose about a central axis of the hose; extruding a continuous bead of plastics material to have a cross-section that defines a lumen at a location within the cross-section; cooling the extruded bead sufficiently to cool the plastics material adjacent the location within the cross-section of the extruded bead to cause the lumen to retain its size and shape within the cross-section; re-heating the extruded bead sufficiently to cause outer surface portions of the plastics material of the extruded bead to become molten; and helically winding the extruded bead onto and about an external surface of the wall to provide the wall a support helix.

摘要: 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.
