Abstract
The clutch disc for a friction disc clutch comprises friction linings attached to a lining carrier by connection elements. The connection elements are provided with a synthetic plastics conical head, seated in a conical opening of the friction lining. A shank, on the side of the lining carrier turned away from the friction lining, has been deformed into a closing head. The portion of the shank forming the closing head can consist of synthetic plastics, too, or can be formed by a metal hollow rivet anchored in the head. The synthetic plastics head wears out along with, and increases, the wearable volume of the friction lining.
