ABSTRACT:
The optical fiber paid out from a reel passes through an extrusion head, then through a cooling vat, the sheath extruded around it being pulled by a withdrawal device. The sheath then passes through a second vat, when the stranding element is withdrawn by an auxiliary withdrawal device under as low a tension as possible. In the second vat, the stranding element is reduced to a temperature lower than the ambient temperature so that contraction of the sheath ensures the excess length of the optical fiber.
