  • Method of manufacturing waved disk for friction engaging apparatus
    Patent number: 6638469
    Abstract: A waved disk for use in a friction engaging apparatus has toothed portions along an outer or inner edge thereof, and is bent or undulated in a direction of the plate thickness with the circumferential direction as the direction of a wave length. In manufacturing the waved disk, there is used a press with a stationary die and a movable die. The stationary die has a plurality of radially elongated pressing portions raised from the surface of the stationary die so as to correspond to highest portions of mountains of the wave. The movable die has a plurality of radially elongated pressing portions raised from the surface of the movable die so as to correspond to lowest portions of valleys of the wave. A disk blank is pressed between the stationary and movable dies for being pressed in the direction of the plate thickness.
