PURPOSE:To place the peripheral edges of conical parts at equal intervals, by fitting the plural conical parts in prescribed positions along a shaft. CONSTITUTION:Numerous parts 41, 41' shaped as flat truncated cones are mounted on a shaft 42 so that the parts are located in prescribed positions along the shaft by adjuster screws 43, 43' provided at both the ends of the shaft. The peripheral edges 44, 44' of the parts 41, 41' are thus placed in prescribed positions at equal intervals. |
