Abstract
PURPOSE: To broadside wind the metallic flat bar into spiral, and to cheaply manufacture the doughnut ring, by setting the stepped spiral guide plate on the circular turntable, and by attaching the pawl, etc., to this guide plate on purpose to fix the flat bar.
CONSTITUTION: The stepped spiral guide plate 2 is set onto the circular turntable 1 rotatable in the arrowed direction; the tip of the flat bar 3 is placed on the guide plate 2 and is fixed with the pawl 4, and the turntable 1 is rotated while the flat bar 3 is being pressed by the press roller 5 and the guide roller 6. Hereby, the flat bar 3 can be easily formed along the guide plate 2 into the spiral form A like as the roll-shell. By cutting or welding, etc., an end of this spiral material, the doughnut ring D can be easily, cheaply manufactured with the lessened material loss as compared with the conventional method.
