Abstract
The invention relates to a mounting mat for mounting an exhaust gas catalytic converter, which is used for purifying motor vehicle exhaust gases, in a catalytic converter housing. The mounting mat has at least three plies and is mechanically compacted by seams () that absorb tensile stresses. The seams () are made with a sewing thread () whose temperature resistance is lower than the temperature of the mounting mat () when the exhaust gas catalytic converter is in operation. According to the invention, an elastically compressible nonwoven () made of crimped metal filaments is placed between two outer plies (') made of mineral fibers ().
