Abstract

PURPOSE: To keep a distance between V-grooves highly accurate shaped by bending areas of small diameter and large diameter in order of a staged cuplike pulley material having large, middle and small diameters, by erasing expansion at an open end which is developed under said shaping.
CONSTITUTION: Before manufacturing, is shaped a two-stage cuplike pulley material 1 of sheet metal having large, middle and small diameters 2W4 from the lower end opening to the upper end wall. An under mold 5 maintains a stage between a small diameter part 4 and a middle diameter part 3. And an over mold 6 depresses a top head wall 7. The small diameter part 4 is turned and pressed in the axial direction by a roller, thereby forming a V-groove 11. With the over mold 14 depressing the large diameter part 2 in the axial direction, the large diameter part 2 is turned and depressed by a roller 15 to shape a preliminary V-groove 16. Thereafter the material 1 is shifted between under and over molds 17, 18 for the last shaping. After a roller 15 is used to form a V-groove 20, an open fringe 13 of the material 1 is shaped with a roller 21.
