A method of eliminating creep in screw joints or riveted joints in a vibration damping so-called laminated sheet, consisting of at least one vibration damping layer of plastic or rubber applied between two metal sheets to a unit, whereupon holes for screws or rivets have been made in the sheet for instance by punching or drilling. The method comprises embossing the laminated sheet from one or both sides around the holes or the prospective holes after or before the formation of the holes, so that the embossing penetrates the damping layer and the sheets are getting a metallic contact with each other, and so that the distance between the sheets is maintained even if the intermediate layer would lose its carrying capacity. |
