Abstract
A braided hose reinforcement (14) comprises left and right turning strips (20, 22). Each of said strips comprises a number of steel wires. The steel wires (24) located at the side regions of the strips have a tensile strength which is substantially lower than the tensile strength of the steel wires of the central region.
Claims11
A braided hose reinforcement comprising left and right turning strips, said left turning strips being bent so that they subsequently run above and under said right turning strips and vice versa, each of said strips having a longitudinal central region and two longitudinal side regions;
- each of said central and side regions comprising one or more steel wires, characterised in that said one or more steel wires of said side regions have a tensile strength which is substantially lower than the tensile strength of said one or more steel wires of said central region.
A hose reinforcement according to any one of the preceding claims, wherein said one or more steel wires of the side regions have a carbon content lower than 0.80%.
A hose reinforcement according to any one of the preceding claims, wherein said one or more steel wires of said side regions are flat wires or wires with a rectangular cross-section.
A hose reinforcement according to any one of the preceding claims, wherein the number of the steel wires in said side regions equals one.
A hose reinforcement according to any one of the preceding claims, wherein the steel wire in the central region have a tensile strength higher than 2800 MPa.
