Abstract
A metal support matrix for a catalytic reactor for exhaust emission control, in particular for internal combustion engines, which includes a plurality of stacks of sheet metal layers, each stack having a central end and a free end, and a jacket which encompasses the stacks. The central ends of the stacks contact each other and the free ends are mutually twisted around a point of symmetry so that the free ends contact the inner surface of the jacket. Prior to twisting, the stacks are in the shape of a rectangle, trapezoid or parallelogram.
