FIELD: mechanical rubber goods; manufacture of flexible high-pressure hoses for handling liquid, viscous and gaseous media.
SUBSTANCE: proposed attachment device has stepped taper projection of flange with circular recesses for receiving 2-16 rings. Twin reinforcing layers of cord are wound with polymer threads or metal wire in zone of taper projection and covering layer of rubber is laid over them. Taper sleeve is split and its both halves are mounted on covering rubber layer and are wrapped with polymer threads of metal wire.
EFFECT: enhanced strength of attachment of flexible hose fittings; improved quality of assembly.
