摘要： An improved hose construction and method of forming the same wherein a reinforcement layer is bonded to a thermoplastic core by a solventless bonding layer defining an inner thermal weld portion substantially autogenous with the outer surface portion of the core tube and an outer portion mechanically interlocked with the confronting inner portion of the reinforcement layer.The bonding layer is thermally formed to be autogenous with the outer surface portion of the core tube and may include an added layer of thermoplastic material which is concurrently fused to define the fused bonding layer. The added layer is compatible with the core tube outer surface portion and is preferably formed of similar thermoplastic material. The reinforcement layer is wrapped about the core tube under tension to provide an embedment thereof in the bonding layer to effect a positive mechanical interlocking therebetween.

摘要： A method of hose production and product wherein a thermoplastic core tube having an outer surface has applied thereto a metallic reinforcement equipped with interstices, the assembly thus achieved being heated in selected portions adjacent the outer surface of the tube to soften the tube for migration into the interstices and thereafter cooling the migrant portions to form a uniform mechanical interlock between the core tube and reinforcement and, further, a uniform mechanical interlock between the core tube, reinforcement and cover.

摘要： A method of forming hose construction utilizing an aromatic polyester thermoplastic core and reinforcing means mechanically bonded about the core with the core portion in which the reinforcing means is embedded being substantially free of stress. A sheath may be provided about the reinforcing means and may be autogenously bonded to "Hytrel", an aromatic polyester thermoplastic body of material coating the reinforcing means.
