Abstract

1. A catalyst carrier body (1) for internal combustion engines consisting of spirally-wound, smooth (4) and/or corrugated (3) sheet-metal strips which are secured in a tubular casing (2) using a jointing technique, characterized in that the matrix of the catalyst carrier body is divided in the longitudinal direction into plurality of cross-sectional sectors (6, 7, 8) by longitudinal slits (5) which extend approximately radially, or in the direction of chords.
