Abstract:
A method of making a friction liner for a dry friction device, the liner having a flat, annular general form and comprising a flat annular body of friction material, the method comprising:winding a band of friction material having a predetermined length, of a mat of said friction material whereby to partly form the body, and further comprising, during the winding step, the further step of joining at least part of a band of reinforcing material to the band of friction material and winding the joined bands, the band of reinforcing material having a length sufficient to constitute at least one annular reinforcing zone, wherein the joining step includes bonding together the band of friction material and the at least part of the reinforcing material prior to winding the bands, wherein the bonding step includes heating the two bands prior to winding the two bands.
