Abstract
The present invention provides a method for manufacturing a plurality of friction plates obtained by adhering friction members to substantially annular core plates, comprising the steps of simultaneously stamping a plurality of coaxial core plates having different diameters with remaining joint portions therebetween, simultaneously stamping a plurality of substantially annular and coaxial friction members having different diameters corresponding to the core plates and with remaining joint portions therebetween to permit adhesion to the core plates, and stamping the joint portions of the friction members and the core plates when or after the friction members are adhered to the core plates.
Claims6
A method for manufacturing a plurality of friction plates obtained by adhering friction members to core plates, said method comprising;
- simultaneously stamping a plurality of substantially annular and coaxial core plates having different diameters with a joint portion remaining therebetween;
- simultaneously stamping a plurality of substantially annular and coaxial friction members having different diameters corresponding to said core plates and with a joint portion remaining therebetween, to permit adhesion to said core plates;
- and
- stamping said joint portions of said friction members and said core plates when or after said friction members are adhered to said core plates.
An apparatus for manufacturing a plurality of friction plates obtained by adhering friction members to core plates, comprising:
- a mechanism which simultaneously stamps a plurality of substantially annular and coaxial core plates having different diameters with a joint portion remaining therebetween;
- a mechanism which simultaneously stamps a plurality of substantially annular and coaxial friction members having different diameters corresponding to said core plates and with a joint portion remaining therebetween, to permit adhesion to said core plates;
- and
- a mechanism which stamps said joint portions of said friction members and said core plates when or after said friction members are adhered to said core plates.
