    摘要: The manufacturing apparatus for optical fiber cord is provided with an extrusion machine, a cooling chamber, an intermediate pulling device, a heating chamber, a final pulling device, and a winding machine wherein the machines, the devices and the chambers are disposed in this order. One or more optical fiber cores and one or more reinforcing fibers are sheathed with thermoplastic resin by the extrusion machine. The thermoplastic resin is solidified by cooling so as to be a resin sheath. The sheathed fibers are annealed by the heating chamber so that its residual stress is relieved.
