Abstract: A damping element shaped as a cylindrical hollow body having an end-side stop and a wall surrounding the body with annular flanges extending around the wall spaced relative to one another. The annular flanges and the wall between the annular flanges have different thicknesses. A method for producing the damping element, includes first producing a blank of the cylindrical hollow body and subsequently upsetting the body to simultaneous shorten it in the direction of the upsetting force by at least 20% of its original length. Then, the walls of the cylindrical hollow body are convexly arched between the annular flanges to form a bellows-like configuration.

Abstract: An aqueous contact adhesive containing an aqueous dispersion of a water-immiscible solvent. The aqueous contact adhesive can contain additives such as preservatives, anti-oxidants, thickeners and thixotropicizing agents, emulsifiers and protective colloids. The contact adhesive has outstanding properties, particularly in regard to the absence of surface tackiness of substrate surfaces coated with the contact adhesive and a high initial tack of the substrate surfaces fitted together under pressure.
