Vibration and sound damping spacers for vehicle brakes and a method of making a web for manufacturing such spacers

摘要

A vehicle brake vibration-and-noise damping insert is comprised of two thin plates and an intermediate damping layer. The damping layer is vulcanized to the two metal plates. A method of producing a material web for the manufacture of this type of insert is also provided. A first sheet-metal strip is coated on one side thereof with a rubber layer, while one side of a second sheet-metal strip is coated with an adhesive. The two metal strips are passed through a band vulcanizing machine with the coated sides of the strips facing one another, so as to vulcanize the rubber layer to the two metal strips.
