Abstract The invention relates to a method for making and reinforcing a catalytic unit intended for purifying exhaust gases, in which method a convolute shaped catalytic unit is formed from a corrugated foil band (2) and a straight foil band (3), placed one on top of the other, by securing the foil bands, coated in advance with both a layer of support material and a layer of catalyst material, to a central shaft (4), around which the catalytic unit is formed. Thereafter, end supports (5) are secured to the ends of the shaft in such a way that they press somewhat to inside the unit and prevent movement of the foil bands in relation to each other.
