Abstract
Elastic band-shaped base ( ) 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 ( ) running parallel to the ground side ( ) 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 ( ) running parallel to the ground side ( ) of the base ( ), in such a way that the smoothed down sides of the tubes ( ) all face the intermediate covering ( ). The inventive design provides for advantageous construction parameters of the elastic base.
