ABSTRACT:
A lined hose has a hot melt adhesive bond between the thermoplastic liner and the outer thermoplastic fabric casing. The method of making this lined hose assembly includes the steps of extruding a tubular thermoplastic liner, applying hot melt adhesive to the liner, cooling and flattening the liner with adhesive, inserting the liner with adhesive into a hose casing, and bonding the liner to the thermoplastic casing by applying heat to melt and activate the adhesive and pressure to form the adhesive bond.
