PURPOSE:To enable the mass production by continuously forming by rolling grooves having circular section with the required radius on both sides biased toward one end of the steel belt having the specified width and thickness as the multiple V-shape metal members that comprise the metal V belt. CONSTITUTION:V-shape metal members 7 are required in geat number for one V belt 6. In order to cope with such, the circular groove 22 for retaining roller membes 12 is formed in advance in the longitudinal direction continuously on both sides 20 of the steel belt by rolling, drawing, extruding or cutting. The V- shape having the open cutting contour 23 having left and right hand inclined sides 8 and indentation 11 for engaging the flexible endless member is formed in the shearing process such as press forming. By this, V-shape members for V belt are efficiently produced in the mass production manner. |
