<p>The method for obtaining mufflers for motor vehicles entails the steps of manufacturing pipes (2,3) each provided with a perforated end (4a,4b) clamped to separator endplates (6a,6b,6c,6d); manufacturing a first half-shell (7) and a second half-shell (8) provided with first and second half-sleeves (12a,12b) for the exit of the imperforate and appropriately shaped end of the pipes (2,3); assembling, by seaming, the first and second half-shells (7,8) so as to define a container, and; sealing the container at the first and second half-sleeves (12a,12b) and at the seam defined between the half-shells (7,8). The method thus allows to obtain a muffler which has no welds. <IMAGE></p> |
