A vehicle brake vibration-and-noise damping insert is comprised ot two thin plates (1, 2) and an intermediate damping layer (3). The damping layer (3) is comprised of a rubber layer (4) which has been vulcanized to the two metal plates (1, 2). The invention also relates to a method of producing a material web for the manufacture or this type of insert. 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.

Pièce d'insertion assurant l'atténuation des vibrations et du bruit dans les freins d'un véhicule. Elle est constituée de deux plaques minces (1, 2) et d'une couche intermédiaire d'amortissement (3). La couche d'amortissement (3) est constituée d'une couche caoutchoutée (4) fixée par vulcanisation aux deux plaques métalliques (1, 2). On a également prévu un procédé de production d'une bande de matériau destinée à la fabrication d'une pièce d'insertion de ce type. On recouvre l'une des faces d'une première bande de tôle d'une couche caoutchoutée, tandis qu'on recouvre de colle l'une des faces d'une seconde bande de tôle. On fait passer les deux bandes métalliques dans une machine de vulcanisation de bandes en s'assurant que les faces revêtues des bandes sont tournées l'une vers l'autre, afin de fixer par vulcanisation la couche caoutchoutée aux deux bandes métalliques.
