Abstract: The article, such as a circular saw tool or a gear wheel, has a visco-elastic synthetic-resin damping layer between, on the one hand, a portion of the body of the article which is integral with, or securely attached to, a work region adapted to interact with another article, and, on the other hand, a counter-element which extends parallel thereto. The damping layer is arranged in the interior of the article in a region covered by an outer member integral with or securely connected to the body. The parts between which the damping layer lies are connected together by the damping layer in a manner which permits shear stresses to occur in the damping layer.

Abstract: A blade with teeth whose spacing varies around the periphery has, on at least one side, a cover element and an intermediate visco-elastic layer, in order to reduce noise. A holding element fixed to a support ring holds the cover element on the blade independently of the intermediate layer and allows the layer to perform a damping function subject to thrusting stresses.

Abstract: Circular saw tool, with a single-ply or multi-ply disc-shaped saw blade and teeth distributed over the circumference thereof, the saw blade being provided on each side with a bonded covering.
