Clutch plate and method of making same
First Claim
1. A friction component including, a facing of friction material, at least one metal section of plate-like form secured to said facing so as to be held against movement relative thereto, said metal section being embedded within a rear surface of said friction facing so as to be exposed at that rear surface and so that the periphery of the metal section is completely surrounded by said friction facing, and at least one hollow fastener formed integral with said metal section and projecting therefrom outwardly away from said rear surface, said fastener providing means whereby said friction component can be attached to a clutch plate cushioning spring.

Abstract
A friction component for a clutch or brake including a facing of friction material and at least one metal section of plate-like form embedded in a rear surface of that facing and having an integral rivet or other fastener projecting outwardly from the facing rear surface. The metal section extends across a relatively small part of the facing rear surface and if there is a plurality of such sections they may be interconnected through integral bands. In the case of an annular friction component the metal sections are spaced circumferentially around the friction facing and if connecting bands are used they are preferably adjacent the inner periphery of the facing.
