Abstract

1. A catalyst support body for internal combustion engines consisting of a supporting matrix with flat (8) and/or corrugated (7) sheet-metal strips which are spirally and, at least in sub-regions, helically wound and are connected to one another and to the inner side of a casing (20) by welding, soldering or sticking, characterized in that the ratio of the width (b) of the sheet-metal strips (7, 8) to the slope(s) of the helix or the diameter of the supporting matrix is so selected that no cross-section through the winding cuts all the sheet-metal strip layers, i.e. the axial spread (h) of the supporting matrix, which is in the form of a hollow cone, is greater than twice the width (b) of the sheet-metal strips (7, 8).
