摘要： A method of hose construction and product formed thereby consisting of an extruded thermoplastic core tube having ferrometallic wire reinforcement windings thereon which are closely wound and providing minute spaces between the wires. The reinforced core tube structure is elevated in temperature by an induction heater which concentrates heating in the wire reinforcement and transfers heat from the wire by conduction to the outer periphery of the core tube. Supplemental conventional heaters may be used in conjunction therewith to achieve substantial temperature elevation of the wire reinforcement. Thereafter a thermoplastic cover is pressure extruded over the heated wire reinforcement and forced through the minute spaces in the reinforcement into engagement with the core tube periphery. Cool-down establishes a bond between cover, wires and core tube and a mechanically locked, integral composite hose structure.

摘要： A hydraulic hose having a single ply of braided wire reinforcement over a rubber core tube. The single ply of reinforcement provides burst strength, impulse resistance and flexibility comparable to that of a conventional hose having two plies of braided wire reinforcement yet utilizes less wire by weight and is smaller in O.D. The single ply of reinforcement comprises braided strands, each strand including a plurality of wires of at least two different diameters symmetrically arranged and providing about 75-95% coverage of the core tube.
