MAGNETICALLY ADHESIVE DAMPING FOIL

摘要

The formation of bilsters on fusing a magnetically adhesive bituminous damping foil, that is privided with a hot melt adhesive layer on the underside to a body sheet at temperatures of apparoximately 190.degree.C is prevented by embedding in the damping foil a flexible foil that is resistant to changes of temperature. For conventional damping foils having a thickness of up to 3 mm, the space between hot melting adhesive layer and foil should not be larger than 1 mm.
