Definitions

  • the invention relates to a molded body of sound-absorbing material composition for installation on rails, preferably on grass rails, which has an engagement region on the rail chamber and a beam area continuously adjacent to the rail.
  • Ventilation holes 26 In the tub bottom 25 are ventilation holes 26 whose edges are raised relative to the tub bottom 25 ( Fig. 1 ). In spite of these ventilation holes, drip water protection for the screw heads 5 ( Fig. 2 ) speak.
  • the task of the ventilation holes 26 and 36 is to ensure that moisture can evaporate below the rail 1 and the molded body 2 and 3 respectively.
  • the opposite of the tub bottom 25 and 35 increased edge of the ventilation holes 26 and 36 impeded that water, sand and other contaminants in the region of the rail 1 and its terminals 5 can pass.
