Abstract (en)
[origin: US6468631B1] Elastic band-shaped base (1) made of rubber or of a material similar to rubber for insulating and absorbing vibrations and impact sound, specially track-bed matting, wherein the base is fitted with spaced tubes (2, 3) running parallel to the ground side (4) of the base on at least two planes (I, II). The tubes have a semicircular, semi-oval, or semi-ellipsoidal cross section. The invention is characterized in that two planes (I, II) are arranged at a distance (A) in relation to each other, irrespective of the total number of the planes of tubes, forming a continuous intermediate covering (5) running parallel to the ground side (4) of the base (1), in such a way that the smoothed down sides of the tubes (2, 3) all face the intermediate covering (5). The inventive design provides for advantageous construction parameters of the elastic base.
