摘要:
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.

A method for producing a structured sheet-metal strip includes feeding a smooth sheet-metal strip to a shaping apparatus along a guiding direction. A primary structure is produced in the smooth sheet-metal strip through the use of the shaping apparatus, during which a number of separate shaping tools act upon the sheet-metal strip in a manner that is substantially perpendicular to the guiding direction. An apparatus for producing a structured sheet-metal strip can produce the structured sheet-metal strips with a particularly low ratio of corrugation length to corrugation height. Such structured sheet-metal strips are used, in particular, for producing purification components in mobile exhaust gas systems.

A housing for an exhaust gas treatment component includes a casing having a first thickness and a first length and at least one sleeve having a second thickness and a second length. The at least one sleeve is at least partially in contact with the outside of the casing and is connected thereto. The second length of the at least one sleeve is shorter than the first length of the casing. An exhaust gas treatment component, an exhaust gas system and a motor vehicle are also provided.

An apparatus and a method for welding metallic fibers to form a knitted fabric having a predetermined width, include feeding a composite of metallic fibers to an apparatus for welding the fibers to form a knitted fabric, and separately welding a plurality of partial sections of the composite in a time period, in which the composite is at a standstill, for example through the use of a plurality of welding electrode pairs which are disposed over the width of the composite. A method for filtering exhaust gases and an exhaust-gas treatment component are also provided.
