Abstract
Device for catalytically purifying exhaust gases from a combustion engine and process for implementing such device. A porous catalyst body bears against the inner walls of a casing above a winding of a metal wire netting. The annular space between the catalyst body (1) and the casing (2) is obturated by means of an annular seal made of a non-inflammable ceramic fibre material, so that such fibre material is pressed inside and between the windings of the wire netting (3). Further, the wire netting is wound with a superposed layer of fibre material.
