<p>A sheeting of multilayer antidrumming lining material, viz. a film containing bitumen or plastic, or a combination film containing bitumen and plastic, which is backed with a wide-meshed fabric having a high tensile strength. This high-tensile fabric backing prevents the antidrumming film, on the one hand, from cracking and, on the other, it holds it even when in a plasticized condition on the upper edge of a steeply inclined or vertical sheet metal component, so that the piece of antidrumming film hanging thereon cannot slide off. Also, due to the backing fabric, the film does not flap away outwardly and upwardly in the area where a steep descent starts. Finally, the tensile strength of the plasticized film is increased such that it cannot crack under the influence of gravity in the area of vertical sides. Where strongly localized form fitting adaptation of the sheeting of antidrumming lining material to the shape of a substrate is required, a few areas of the sheeting of antidrumming lining material do not have any backing material. Also cutaway portions which are adapted to the requirements of the curved sheet metal component to be deadened can be provided. Advantageously, the edges of the cutaway portion are also reinforced with extra pieces of a wide-meshed fabric to afford additional protection against deformation.</p> |
