Abstract
PURPOSE: To elongate a shaft material with idle rollers revolving together with a ring and simplify the device by disposing the plural idle rollers in the ring with inclination with respect to the central axis of the ring.
CONSTITUTION: Plural idle rollers 5 in the bore of a ring 4 are distributed equally on the single hyperbolic surface of rotation centering at the central axis of the ring 4. The centers of the rollers 5 are inclined by an angle β to the central axis of the ring 4. Next, the ring 4 is rotated by a motor 1 and a shaft material 7 is inserted into the central space formed by the plural rollers 5. Then, the rollers 5 revolve while contacting the outside circumference of the shaft material 7 by the revolution of the ring 4 and the shaft material 7 is elongated by the feeding force of a pusher 6.
