ABSTRACT:
In order to provide a substrate such as an optical preform rod (24) which suitable for insertion into a tube and which has a transverse cross section that is substantially circular and disposed concentrically about a longitudinal axis of the substrate substantially along its entire length, a force-applying means such as a graphite roller (52) is adapted to be moved incrementally toward an axis of rotation (35) about which the preform rod is turned rotatably. Movement is discontinued when there is an indication that the force-applying means has been in continuous engagement with the preform rod for at least a predetermined portion of the periphery of the rod. In a preferred embodiment, the engagement of the force-applying means and the preform rod is discontinued after a predetermined time whereafter the force-applying means again is moved toward the axis of rotation. Cycles of engagement and disengagement are continued as relative motion is caused between the force-applying means and the preform rod in a direction along the axis of rotation.
