Date Nov. 17, 1988.An endless flexible press jacket for a press roll, a process for its fabrication and an apparatus upon which it is fabricated. The press jacket comprises a radially inner layer of elastomeric material which is provided with embedded layers of reinforcing yarns, an inner longitudinal layer of yarns extending under tension between the lateral ends of the endless tubular press jacket and a helical winding of peripheral yarns pretensioned and wrapped around the longitudinal yarns. The longitudinal yarns are held pretensioned radially above a casting mandrel and the casting nozzle moves along the axis of the casting mandrel delivering a helix of castable jacket material around the casting mandrel. At the same time, the later peripheral yarns are applied into the longitudinal yarns in the applied jacket material.
