The present invention relates to an exhaust-gas treatment device (1) with a honeycomb element (2), through which an exhaust gas can flow, and which honeycomb element (2) is wound and/or stacked with at least partially structured sheet-metal layers (3, 17) in such a way that channels (7) are formed, through which an exhaust gas can flow in the axial direction (4) from an inlet side (5) to an outlet side (6). A first part (8) of the sheet-metal layers (3, 17) ends flush at a first end surface (9) which is assigned to the inlet side (5) and/or the outlet side (6), and a second part (10) of the sheet-metal layers ends at a second end surface (11) which is likewise assigned to the inlet side (5) and/or the outlet side (6). The second end surface (11) is at a spacing (12) from the first end surface (9), by a first length (13) in the axial direction (4) of the first part (8) of sheet-metal layers (3, 17) being greater than a second length (14) in the axial direction (4) of the second part (10) of sheet-metal layers (3, 17). As a result of the spacing (12) between the first end surface (9) and the second end surface (11), a receptacle (15) is formed, in which a heating element (16) is arranged. By way of the present invention, an electrically heatable exhaust-gas treatment device (1) can be produced in a simple way, into which a heating element (16) can be integrated during or after the production of the honeycomb element (2). |
