摘要： An upstream twisting inhibiting roller, a twist non-inhibiting roller, a twist provider and a downstream twist inhibiting roller are provided in this order along the path line of a coated optical fiber. The twist provider provides the twist to the coated optical fiber. The upstream twist inhibiting roller and the downstream twist inhibiting roller respectively inhibit a rotation of the coated optical fiber around the axis of the coated optical fiber. The twist non-inhibiting roller does not inhibit the rotation of the coated optical fiber around the axis of the coated optical fiber.

摘要： A method and a system based on the method imparts to an optical fiber a predetermined rotation about its axis, wherein the fiber is rotated by way of a frictional force acting on the fiber while it is advanced in a predetermined direction. The rotation actually imparted to the optical fiber is measured on-line while the fiber is advancing in the direction and the frictional force is controlled responsively to the measured rotation so as to obtain the predetermined rotation. Spinning devices acting on the optical fiber by way of an externally controllable frictional force and particularly suitable to be used with the method are disclosed.
