  • PROGRESSIVELY STAMPED CLIP-ON NOISE DAMPING SHIM FOR FRICTION ASSEMBLY, AND METHOD AND APPARATUS FOR PRODUCING CLIP-ON NOISE DAMPING SHIM
    Publication number: 20140138192
    Abstract: A noise damping shim for a friction assembly is produced by a pre-slit step and a bend and blank step. The pre-slit step forms pre-slits in a shim material at locations where tabs of a noise damping shim are to be formed. The bend and blank step bends each of the tabs at a bent angle relative to the shim material while simultaneously blanking a shim body from the shim material to produce a noise damping shim having bent tabs extending outwardly from a periphery of the shim body.
