1) L, then the butt end (11a) of the approximately cylindrical material
(11a) were joined using micro plasma welding (Fig. 1), and then the joined cylindrical body material No. 0 was cut into circular slices of a predetermined width using a cutting wheel (+4) (Fig. W ),
An endless metal band base material (+6) was formed (Fig. They manufactured endless metal bands.

The edge between the two ends of the cylindrical material (1 m (+61%) becomes scrap. Only a few endless metal bands can be made from one sheet, resulting in material loss or a large amount of tK.
