Abstract: A brake hose has an inner tube layer made from a rubber material, a lower thread layer made of braided lower threads, an intermediate rubber layer, an upper thread layer made of braided upper threads, and a skin rubber layer. The lower thread layer is constituted by lower threads each having a first adhesive thin film adhesively bonded to the inner tube layer and to the intermediate rubber layer. The upper thread layer is constituted by upper threads each having a second adhesive thin film adhesively bonded to the intermediate rubber layer and to the skin rubber layer.

Abstract: A reinforced rubber hose having a layer of ethylene-propylene rubber outside or inside a fiber-reinforcing layer. The two layers are firmly bonded to each other by an extruded adhesive layer of butyl rubber which exhibits a high bond strength after vulcanization. This obviates the necessity of treating (usually by dipping) the fibrous reinforcement with an adhesive before its braiding or knitting.
