Abstract (en)
[origin: WO2006095373A1] A method for filling with sound absorbing material (1) the mufflers of internal combustion engines. The sound absorbing material (1), normally consisting of glass fibre, is wound - according to the method of the invention - around a reel- winder or simply around a tube with a diameter corresponding to the distance between the baffles which delimit (confine) the ducts (2) of the muffler. The length of the reel-winder or the tube is equal to the total circumference of the ducts (2) around which the fibre will be wound in order to obtain a soundproofing mass specifically realised to fill up the volume. The soundproofing mass obtained in this way, after its extraction from the tube or reel-winder on which it was wound, will first be squeezed and thereafter sewn in one or more of its parts, to facilitate its handling.
