Claims
- 1. A process for producing a metallic honeycomb body, which comprises:winding, laminating or intertwining at least one at least partly structured layer of sheet metal to form a matrix; placing the matrix in a tubular jacket having a peripheral surface and a circumferential direction, to form a honeycomb body; placing the honeycomb body between at least two pressure elements spaced-apart by a mutually variable distance, and rotationally driving at least one of the pressure elements; and elastically deforming at least the tubular jacket by successively exerting a substantially linearly and substantially radially inwardly directed force on the peripheral surface of the tubular jacket, as seen in the circumferential direction of the tubular jacket.
- 2. The process according to claim 1, which further comprises providing the at least two pressure elements, between which the honeycomb body is placed, as at least three cylindrical pressure elements rotatable about respective axes.
- 3. A process for producing a metallic honeycomb body, which comprises:winding, laminating or intertwining at least one at least partly structured layer of sheet metal to form a matrix; placing the matrix in a tubular jacket having a peripheral surface and a circumferential direction, to form a honeycomb body; placing the honeycomb body between two plate-shaped pressure elements spaced-apart by a mutually variable distance, and translationally moving the pressure elements relative to and substantially parallel to one another by fixing one of the plate-shaped pressure elements in place and moving the other of the plate-shaped pressure elements; and elastically deforming at least the tubular jacket by successively exerting a substantially linearly and substantially radially inwardly directed force on the peripheral surface of the tubular jacket, as seen in the circumferential direction of the tubular jacket.
- 4. A process for producing a metallic honeycomb body, which comprises:winding, laminating or intertwining at least one at least partly structured layer of sheet metal to form a matrix; placing the matrix in a tubular jacket having a peripheral surface and a circumferential direction, to form a honeycomb body; placing the honeycomb body between two plate-shaped pressure elements spaced-apart by a mutually variable distance, and translationally moving the pressure elements relative to and substantially parallel to one another by moving the plate-shaped pressure elements in opposite directions; and elastically deforming at least the tubular jacket by successively exerting a substantially linearly and substantially radially inwardly directed force on the peripheral surface of the tubular jacket, as seen in the circumferential direction of the tubular jacket.
