ABSTRACT:
A vibration damper is formed from two metal layers. The first metal layer is coated with primer layers, slit, and partially stamped to form a strip holding a plurality of vibration damper blanks. Each of these blanks has a body portion and tab portions. A second metal layer is formed separately by coating a second metal strip with adhesive and stamping it to form a plurality of vibration damper blanks but without tabs. The two strips are aligned, bonded together and the vibration dampers are formed and stamped out. (The tabs, which are only on one layer, are bent to form clips.) Due to this construction the clips cannot delaminate and provide a noiseless metal contact with the shoe plate, while an improved adhesive can be employed to bond the two metal layers together.
