ABSTRACT:
There is disclosed herein a method and apparatus for fabricating a pulley which the pulley rim is fabricated from a cylindrically-shaped blank of constant diameter which is deformed by relatively movable die forming members so as to form a ring having a V-shaped cross section which may then be assembled to a hub member. Auxiliary forming dies are also disclosed which may assist in the proper formation of the V-shaped cross section. In another form, the pulley rim is fabricated with multiple annular V-grooves. Apparatus effective for carrying out the above method is also disclosed herein.
