Abstract

The invention relates to a magnetically adhering damping film having improved damping properties and a lower ferrite proportion and a method for its production. The magnetic mass is, in this case, let into the surface of the damping mass layer in strips on one side. The whole magnetic mass is magnetised, in contrast to the known two-layer film.
