Abstract: A method and apparatus for continuously manufacturing thin-walled flexible hoses having helical reinforcement members which are relatively strong in relation to the hose walls wherein an internal pressure is applied to the hose core to obviate the need for a manufacturing mandrel, and a plurality of turns of the reinforcement member are coiled onto a fixed tube through which the hose core passes and the successive comparatively unstressed turns of the reinforcement member are applied to the slightly expanding hose core at the tube exit by the application of an intermittent pressure in an axial direction against the respective last turn of the plurality of turns on the tube.
