发明名称 Helical wire reinforced hose
摘要 A flexible reinforced cured resin hose is shown having a combination of helically wound cable wires and body wires embedded therein in layers in the wall forming the hose. Two plies of cable wires are wrapped in opposite directions around the periphery of a liner tube supported on a mandrel, the plies being supported in a resin filler layer applied over the liner to hold the wires spaced apart to prevent the wires from rubbing as the hose is flexed. The body wires are more widely spaced apart and are spaced from and wrapped over the layers of cable wires to be embedded in the resin filler layer. A breaker layer may be wrapped over the assembly, an outer layer of wear resistant neoprene is applied and then a nylon cure tape is applied over the entire assembly prior to curing. A nylon rope is also spiraled down the outside of the assembly to be positioned exactly midway between the spaced apart body wires and then the resin is cured under heat and pressure. The nylon cloth shrinks to force the resin and wire components into a solid mass and the nylon rope shrinks even more to produce a spiral groove around the periphery of the finished hose product that has a tought flat surface extending throughout the flat surface outside the groove.
