<p>This invention relates to hoses reinforced by metal cables. According to the invention, the reinforcement comprises two or more cables separated by a rubber layer, these cables being helically wound to form, with the axial direction of the hose, an angle equal to or greater than 70 DEG , and preferably equal to or greater than 80 DEG . The layers are crossed and the cables of one layer form, with the hose axial direction, an angle equal to and of sense opposite to that of said axial direction and the cables of said other layer. Supplementary reinforcement may be provided, if required, and comprising an extra thicker metal wire that is helically wound so that its convolutions form an angle not less than 80 DEG with the hose axis or, alternatively, laminated rings located at right angles to the hose axis and constituted by concentric windings of metal strips: such supplementary reinforcement is located in the rubber layer located between the said cable layers.</p> |
