ABSTRACT:
A high pressure hose construction and method of and apparatus for making the same is disclosed wherein the hose construction has a smooth walled inner liner of resilient polymeric material, and an adhesive layer, which may also be of polymeric material bonded to the liner. A braided cover is disposed over the entire layer and embedded therein. This braided cover is comprised of a plurality of elongated intermeshing strands of non-metallic fibers, such as yarn, and metallic fibers. Preferably, every three strands are of flexible, non-metallic fibers, such as nylon fibers, and every fourth strand is of metallic fiber, such as piano wire or spring steel. One set of strands crosses over and under another set to produce an intermeshing or weaving effect. These strands may also extend in a direction at an angle, such as 45.degree. or 53.degree., to the longitudinal axes of the liner, to improve the bend radius and prevent ballooning or extensions or the like of the finished hose construction when used in high pressure applications.
