FABRICATION OF FRICTION ELEMENTS

摘要

An annular preform (18) for a clutch friction facing is wound from an impregnated filament (11) on a rotating face plate (17) and held and consolidated by a non-rotating tailstock pressure plate (20) through which the filament passes to the face plate. To ensure that the leading end of the filament is properly attached to the rotating plate and laid down in the proper (lobed) pattern against centrifugal and shear forces and that subsequently deposited filament adheres to itself when consolidated by tailstock pressure from rollers (29') etc. thereof, the tailstock pressure plate also carries temperature controlled sliding plate (32) which can heat (or cool) the rotating preform to optimise the sticking properties of the filament and augment or counter heat generated by frictional rubbing against the preform.
