Abstract: A method for producing a honeycomb body having a honeycomb structure disposed in a housing, includes at least forming a honeycomb structure, inserting the honeycomb structure into a housing, carrying out a heat treatment operation on the honeycomb structure having the housing, contacting outer regions with a molding, at least during the inserting step or the heat treatment step, and reproducing a desired outer contour of the housing with contact faces of the molding. A molding and an exhaust gas treatment unit produced with a thin housing in a dimensionally accurate manner, are also provided.

Abstract: A method for brazing a metallic honeycomb body (1) for exhaust gas treatment, includes at least: a) pretreatment of a honeycomb body (1) at a temperature above 400° C.; b) cooling the honeycomb body (1); c) brazing the honeycomb body (1) at a temperature in a range of from 1050° C. to 1100° C. under atmospheric pressure; and d) cooling the honeycomb body (1). A suitable apparatus for carrying out the method is also provided.

Abstract: 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.

Abstract: A housing for an exhaust gas purification component encloses an interior space in which at least one receptacle is formed by the housing at the outside. An exhaust system includes at least one first exhaust line section and the housing having the exhaust gas purification component. The first exhaust line section is in engagement with the receptacle, and the first exhaust line section and the receptacle are connected to one another in a materially integral manner. A motor vehicle having the exhaust system is also provided.

Abstract: A filter layer includes at least partially gas-permeable material having a plurality of segments joined to one another in such a way that the filter layer has non-parallel edges. Inexpensive manufacturing methods for such a filter layer, conical honeycomb bodies having the filter layer and particle-filtering exhaust gas purification apparatuses for motor vehicles, are also provided.

Abstract: A honeycomb body includes two opposite end sides, at least one housing and at least one metallic layer forming channels. At least one of the end sides has at least one brazed zone forming a belt-shaped, brazing material-free zone adjacent the housing. A method for producing the honeycomb body, an exhaust-gas treatment component for an internal combustion engine and a motor vehicle having the honeycomb body, are also provided.
