Abstract
A preform suitable to be cured to form a friction element, such as clutch facing, is produced by winding a filament, or a tape containing curable material on to a surface of a rotating plate. The filament, or tape, is guided on to the surface by a guide which is movable in a plane. A signal, representative of the angular position of the plate, causes generation of a demand signal indicating the desired position of the guide. A closed loop control, controls the movement of the guide to give a predetermined winding pattern. The control causes the guide to move as a function of the demand signal and a feedback signal representative of the position of the guide. The curable material in the preform is then cured.
