METHOD AND APPARATUS FOR MAKING REINFORCED HOSE

摘要

A method for continuous production of reinforced, elastomeric high pressure hose having an inside diameter greater than 50 mm comprising extruding the hose onto a stationary mandrel over which the hose rollingly or slidingly passes in a continuous manner. Wire reinforcing is wrapped around the extruded hose as it is passing over the mandrel. Apparatus for carrying out this method is disclosed where the stationary mandrel may be the type having a plurality of roller barrels, a hydrostatic or aerostatic mandrel. or a mandrel having a plurality of endless flexible bands. Antirotational means is provided on the mandrel to prevent twisting of the extruded hose and the inaccurate laying of the wire reinforcing around the hose. The method provides a continuous length of high pressure hosing which can withstand hydrostatic pressures on the ocean floor. The apparatus is compact so that production of the hose can be carried out aboard ship when laying hose on the ocean floor.
