<p>A honeycomb structure, in particular a catalyst support, preferably of circular, oval or elliptical cross-section, is made of a pile of sheet metal plates (1, 2) intertwined in opposite directions and arranged in a tubular sheath (7). To stabilize the entire structure and to prevent extraction of the sheet metal plates (1, 2) from the tubular sheath (7), some of the sheet metal plates (8, 9, 10) are thicker than the others, because these layers (8, 9, 10) are made of thicker sheet metal or a plurality of contiguous thinner sheet metal plates. The thicker sheet metal layers stabilize the entire structure and prevent, in particular, deformation of the tubular sheath due to high internal pressure at elevated temperatures, even in structures of oval or elliptical cross-section.</p> |
