Abstract

High-pressure hose consisting of an inner core with a wire reinforcement and an outer sheath is produced by injecting a rubber mix over a plastic mandrel, braiding the core and applying the sheath. Before the last operation, the blank is quickly heated to 200-300 deg.C as measured at the wires, for 15-40 sec and held at a temperature of over 150 deg.C for at least 30 sec. This ensures a secure adhesion between inner core and outer sheath with the inserted wires in an operation which can be integrated in a normal production line.
