As a method of obtaining a lightweight and highly rigid ring reinforcement for the ring-shaped rim of a steering wheel, which is generally subjected to bending and torsion, for example, a thin carbon fiber of 0.2 to 0.5 mm is applied to the central part of the ring in order to increase the bending rigidity. A prepreg tape made of unidirectional fiber-reinforced plastic such as or glass fiber is oriented, and another prepreg tape is wound over the ring at a certain angle and pitch to increase the torsional bending strength. A rigid ring reinforcement is obtained.

A toroidal winding machine finely winds a single coil wire with a round cross section around an iron core, and obtains magnetic force by changing the number of turns.
In addition, ring bandaging machines wrap the tape around the bandage product, but in both cases, a thin prepreg tape is oriented around the circumference of the ring, and another prepreg tape is oriented on top of it at a fixed angle and pitch. Furthermore, it is not possible to line up and wind multiple tapes at the same time.
