In this state, the polishing wheel (3) f! : Gradually press against the surface of the vulcanizing sleeve (10) while rotating it in the opposite direction of the rotation direction of the drive drum (1). As a result, first, in the circumferential direction of the vulcanized sleeve, the ■-shaped grindstone (4) of the polishing wheel (3) is applied to the surface of the vulcanized sleeve.
The shaped grooves (14) are cut down, and a plurality of belt compression parts (8) extending in the circumferential direction are formed on the surface of the vulcanized sleeve between the V-shaped grooves. ■With this polishing wheel (3)
As the depth of the groove increases as the groove formation process progresses, the positioning roll (which had been press-fitted in advance on the surface of the vulcanized sleeve)
11), the ■-shaped protrusions (12) of the rolls fit into the V-grooves, preventing movement of the vulcanized sleeve (10) immediately before the polishing wheel (3), and improving the accuracy of ■-groove polishing. (See Figure 3) In this way, a connecting belt (15) in which multiple row edge belts are connected is obtained as shown in Figure 8, and then each type of pitch is determined from the side where the grooves are formed. The tensile body (7) is embedded in the adhesive rubber (6) as shown in FIG. 4 by cutting simultaneously with multiple blades (16) or sequentially at a feeding pitch with a single blade. A plurality of low 4° edge V-belts (17) having compressed rubber (8) in the lower part and rubberized canvas (5) attached to the upper part are obtained.
