ABSTRACT:
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.
