  • Heated hose for carrying molten thermoplastic material
    Publication number: 20050008353
    Abstract: A hose for transferring heated liquid, such as molten thermoplastic material. The hose includes a conduit that has an inlet end adapted to couple with a source of heated liquid, such as a heated supply tank, and a discharge end adapted to couple with a liquid dispensing apparatus, such as an applicator gun. In one embodiment, the hose may be covered by a woven outer sheath of polyamide that protects the underlying hose against abrasion damage. In another embodiment, the hose may include a hose cuff mechanically coupled with the liquid dispensing apparatus to bolster resistance to axial tensile forces and bending forces applied to the hose.
