    摘要: An encased catalyst, especially for motor vehicles, includes at least one metal honeycomb catalyst carrier body through which exhaust gas can pass. At least one inner jacket tube carries the at least one catalyst carrier body. An outer jacket tube approximately concentrically surrounds the at least one inner jacket tube at a distance. The at least one inner jacket tube and the outer jacket tube have end regions and are firmly joined together in one of the end regions. The at least one inner jacket tube is freely longitudinally expandable in the outer jacket tube.

    摘要: A process for producing a structure in a smooth sheet-metal strip includes multiple process steps. In a first step, a first section of a smooth sheet-metal strip is fed to a first tool and a second section of the sheet-metal strip is fed to a second tool in a direction of advance. Then the sheet-metal strip is stopped. A sheet-metal machining of the first section of the sheet-metal strip is carried out using the first tool. A sheet-metal machining of the second section of the sheet-metal strip is carried out using the second tool, with the first feeding step being carried out simultaneously. An apparatus is provided for producing a sheet-metal strip of such a complex structure, which produces the structure with a very high degree of accuracy even when the materials properties differ.

    摘要: A honeycomb body includes an inlet end side and an outlet end side. Metal sheets are wound, intertwined and/or layered into a multiplicity of sheet metal layers being at least partially structured to form channels leading from the inlet end side to the outlet end side. Edges of at least some of the sheet metal layers have cutouts formed therein at the inlet end side and/or the outlet end side, resulting in a fissured structure of the inlet end side and/or the outlet end side. As a result, only the smooth metal sheets or only the structured metal sheets or both can be provided with the cutouts. Additionally, at least some of the metal sheets can be made of a porous material, in particular compressed metal fibers. Deposition of soot particles on the end sides of the honeycomb body is, to a large extent, prevented due to the cutouts.

    摘要: A catalyst carrier body has a geometrical longitudinal axis, a honeycomb body and a housing. A corrugated casing with an outer side and an inner side is disposed between the honeycomb body and the housing. The corrugated casing is connected to the housing at attachment sections on the outer side thereof by brazing. The attachment sections lie substantially on a common circumferential line and have the narrowest possible width in direction of a longitudinal axis. The attachment sections have an overall surface area permitting them to securely hold the honeycomb body under operating conditions. A high retention degree for the connection between the honeycomb body and housing can thus be achieved even with a shrinking of the diameter of the honeycomb body at end sides during the service life thereof.

    摘要: A method for the production of a converter-carrier body having a metallic honeycomb body made of a plurality of metal layers, especially smooth layers and corrugated layers, the layers having layer ends, such that an outer shape of the honeycomb body is formed by the layer ends. At least one stack is produced having several alternately disposed metal layers that are structured such that channels are formed for a fluid to flow through. The at least one stack is transformed into a honeycomb body having a cylindrical form. The honeycomb body is deformed from the cylindrical form so that an outer shape that deviates from the cylindrical form is produced. Additionally, the invention relates to a corresponding converter-carrier body and a tool for the production thereof.
