Abstract
PURPOSE: To obtain the pressure rubber hose having no rugged part on the surface thereof and pertinent to the property of bonding between layers by a method wherein a half-valcanized inside rubber tube is formed with a multitude of grooves on an outer surface thereof and an unvalcanized rubber tube is formed thereon through an unvalcanized rubber sheet and a fibrous reinforcing layer, thereafter, all of them are valcanized by steam directly.
CONSTITUTION: A rubber blended substance is extruded and formed into a tubular shape to form an unvalcanized rubber tube having a multitude of grooves 5 extending longitudinally on a whole outer periphery thereof uniformly. The half-valcanized inside rubber tube 1 is obtained by heating and valcanizing this unvalcanized rubber tube in a valcanizing boiler. A bonding agent is coated on the outer periphery thereof, the unvalcanized rubber sheet 2 for bonding is wound and laminated on the outer periphery thereof and the fibrous reinforcing layer is braided closely thereon. Further, all of them are passed through an extruder to form the unvalcanized out- side rubber tube 4. The rubber hose thus obtained is valcanized in the valcanizing boiler by steam directly, thus, the pressure rubber hose may be obtained.
