ABSTRACT:
A method and a device produce a fleece of metallic fibers in a layer in which the metallic fibers are welded to one another to form the fleece. A welding process is repeatedly carried out with regard to a portion or section of the fleece. Such metallic fiber fleeces are used, in particular, for exhaust gas treatment units in the automobile industry.
