An apparatus for catalytically decontaminating exhaust gases, preferably for motor vehicle engines, includes a metal carrier body having a plurality of corrugated, or smooth and corrugated, sheet metal layers. The sheet metal layers have smooth end segments overlapping one another and being disposed as an outer layer on the periphery of the metal carrier body. A jacket encompasses the metal carrier body. At least one weld seam may simultaneously connect the smooth end segments to one another and to the jacket. A mechanical retaining device may form-lockingly secure the metal carrier body in the axial direction in the jacket while engaging an end surface of the outer layer. A method for producing the apparatus includes initially coating individual corrugated, or smooth and corrugated, sheet metal layers of a metal carrier body with a wash coat, except for uncoated regions of lengthened smooth end segments of the sheet metal layers overlapping one another and being disposed as an outer layer on the periphery of the metal carrier body. The sheet metal layers are intertwined and inserted into a jacket encompassing the metal carrier body. The sheets are simultaneously connected to one another and to the jacket in the uncoated regions of the lengthened, smooth end segments resting on one another with at least one weld seam.

A method for producing a honeycomb body includes the following steps: forming or winding a multi-layer hollow coil from at least one sheet-metal strip which has at least partial structuring; deforming the multi-layer hollow coil from the outside thereof towards the inside at at least three lines such that the at least one sheet-metal strip extends in loops between outer and inner reversal lines; and compacting the resulting deformed multi-layer structure about the inner reversal lines by rotationally intertwining the loops formed by the folded sheet-metal layers in a given direction.

An exhaust gas catalytic converter, particularly for an internal combustion engine, includes a flow channel for carrying exhaust gas. A carrier body is disposed in the flow channel and has a structure through which exhaust gas can flow. The carrier body is formed of sheet-metal layers. At least some of the sheet-metal layers are at least partially structured. A catalytic coating is disposed in the carrier body. At least one separate heating element in addition to the structure, is adapted to the shape of one of the at least partially structured sheet-metal layers, is electrically insulated from the structure and is in close thermal contact with at least one of the coating and the sheet-metal layers, for electrically heating the carrier body externally. A method for producing an exhaust gas catalytic converter includes placing spaced-apart heating elements adapted to a shape of a corrosion-proof structured sheet-metal layer into the structured sheet-metal layer. At least one other sheet-metal layer is then wound, looped or layered with the structured sheet-metal layer to form a carrier body.

A metal honeycomb body is disposed within a jacket member. At least partly structured sheet-metal layers are wrapped around one another and extend alternatingly back and forth in a curved, preferably involute, fashion between an outer annular region and an inner annular region of the honeycomb body. The sheet-metal layers form loops. At least three reversal lines are defined in the outer annular region, and the sheet-metal layers are intertwined about these reversal lines. A method for producing the honeycomb body includes the following steps: forming or winding a multi-layer hollow coil from at least one sheet-metal strip which has at least partial structuring; deforming the multi-layer hollow coil from the outside thereof towards the inside at at least three lines such that the at least one sheet-metal strip extends in loops between outer and inner reversal lines; and compacting the resulting deformed multi-layer structure about the inner reversal lines by rotationally intertwining the loops formed by the folded sheet-metal layers in a given direction.

A metal support matrix for a catalytic reactor for exhaust emission control, in particular for internal combustion engines, which includes a plurality of stacks of sheet metal layers, each stack having a central end and a free end, and a jacket which encompasses the stacks. The central ends of the stacks contact each other and the free ends are mutually twisted around a point of symmetry so that the free ends contact the inner surface of the jacket. Prior to twisting, the stacks are in the shape of a rectangle, trapezoid or parallelogram.

Catalytic converter carrier bodies have a jacket and adjacent layers of corrugated or smooth and corrugated metal foils wound or layered in the jacket. The metal foils contact each other and contact the jacket at connecting points, defining flow channels between the metal foils and between the metal foils and the jacket and defining brazing gaps at the connecting points. A method for brazing the carrier bodies includes initially dispersing powdered brazing material with a suitable particle size in a mixture of binder material and liquid. The flow channels are flooded with the liquid mixture for depositing the brazing material in at least some of the brazing gaps. Excess mixture is subsequently removed from the flow channels and the carrier body is then brazed.

A process and an arrangement for producing a supporting body for a catalytic reactor is disclosed. In order to reduce thermal stress between the casing tube and the wound metal supporting body of an exhaust gas catalyst, the temperatures of which vary significantly during operation, it has been proposed to provide the ring-type composite of metal strips fastened in a casing tube with slots extending in longitudinal direction. This type of production results in high expenditures. The new process and arrangement of the invention provides that incisions are made directly into the metal strips before the winding or folding of the supporting body, so that a subsequent processing becomes superfluous. The thus produced supporting bodies have a plurality of incisions extending within the ring-type composite which can also prevent the buildup of thermal tensions or stress. The new supporting bodies are used for exhaust gas catalysts of motor vehicles.

A carrier matrix wound of a carrier strip having undulations in its transverse direction has deflections of the carrier strip, said deflections being arranged in planes. During the winding process, the deflections are created by the insertion of deflection pins between the corresponding winding layers. The deflections pins, in this case, are inserted between the winding layers as a function of the desired cross-section of the carrier matrix so that after the winding process and after the removal of the deflection pins, the carrier matrix can be inserted into a sheath that has the desired cross-section of the carrier matrix. By combining several winding bodies of this type into one carrier matrix, arbitrary cross-sections of carrier matrices can be produced, particularly cross-sections having concave archings. During the making process, the deflection pins are fitted through the corresponding bores of two winding disks that are connected with one another in a torsionally fixed way. The carrier matrix that is produced in this way can then be inserted into a sheath. This can be accomplished by a funnel-shaped arrangement.

A heat exchanger wherein a plurality of individual tubular parts are connected with each other is provided having a common pressure element for tube connections arranged in a plane. According to FIG. 1, a pressure platen 6 is present, which consists of a material harder than that of the external tubular part and is equipped with a number of orifices 7 corresponding to the number of tube connections. The pressure platen 6 surrounds the outer and inner tubular parts inserted in each other, and the diameter of the orifices 7 is smaller, at least in part, than the external diameter of the outer tubular part. According to the process for the manufacture of the heat exchanger, all of the tube connections are produced simultaneously by means of pressing on the pressure platen. Each of the tube connections is effected by reducing the cross section by means of plastic deformation of at least the outer, tubular part, whereby a press fit of the tubular part is obtained.
