A head for the simultaneous laying of optical fibers within a grooved cylindrical support rod comprises a hollow tube through which the support rod is capable of passing longitudinally, a draw-ring rigidly fixed to and in axial alignment with the tube. A central opening of the draw-ring has an internal flange provided with radial projecting portions each adapted to rest on the bottom of one groove of the support rod. A member for inserting the optical fibers within the grooves of the support rod has a central opening which is in alignment with the central opening of the draw-ring and through which the support rod is displaceable in continuous translational motion.
