Abstract: A method for producing continuously a long reinforced hose having a plurality of reinforcement layers. An inner reinforcement layer is formed by braiding steel wires or fibers on a mandrel and a rubber is extruded onto the inner surface of the reinforcement layer to form an inner rubber layer therein. An adhesion rubber is then extruded onto the outer surface of the inner reinforcement layer to form an adhesion rubber layer thereon and at the same time an outermost reinforcement layer is formed on the adhesion rubber layer by braiding on a mandrel. The unvulcanized hose including the respective layers is pulled at a speed higher than the braiding speed of the outermost reinforcement layer, thereby firmly joining the reinforcement layers and then pulled at a lower speed but still higher than the braiding speed, thereby more firmly urging both the reinforcement layers to each other.
