ABSTRACT:
This invention comprises a method for manufacturing elastomeric high pressure hose having reinforcement in the form of braided or spiral wrapped textile yarns between extruded inner and outer elastomeric layers. The method includes the steps of extruding the inner elastomeric layer over a long flexible mandrel up to about 1000 ft in length coextensively therewith, then progressively freezing portions of the layer and braiding or spiral wrapping a textile reinforcement thereover. The layer is frozen to prevent extrusion of the inner layer during the braiding. Thereafter additional elastomeric and textile layers are applied and the elastomers are vulcanized in an elongated continuous vulcanizer.
