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; 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 placing the honeycomb body between at least two pressure elements spaced-apart by a mutually variable distance, and driving at least one of the pressure elements.
- 3. The process according to claim 2, which further comprises moving at least one of the pressure elements translationally.
- 4. The process according to claim 3, which further comprises providing the at least two pressure elements as two plateshaped pressure elements, and carrying out the moving step by moving the plate-shaped pressure elements relative to and substantially parallel to one another.
- 5. The process according to claim 4, which further comprises carrying out the moving step by fixing one of the plate-shaped pressure elements in place and moving the other of the plateshaped pressure elements.
- 6. The process according to claim 4, which further comprises carrying out the moving step by moving the plate-shaped pressure elements in opposite directions.
- 7. The process according to claim 2, which further comprises moving at least one of the pressure elements rotationally.
- 8. The process according to claim 7, 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.
- 9. An apparatus for producing a metallic honeycomb body having a tubular jacket with a periphery defining a peripheral surface and having a matrix disposed in the tubular jacket and wound, laminated or intertwined from at least one at least partly structured layer of sheet metal, the apparatus comprising:
at least two pressure elements movable relative to one another and at least two of said at least two pressure elements spaced apart by a variable distance from one another, for receiving the honeycomb body between said at least two pressure elements and bringing said at least two pressure elements to bear against the peripheral surface of the tubular jacket, to successively exert a substantially radially inwardly directed force on at least part of the periphery of the tubular jacket for elastically deforming at least the tubular jacket.
- 10. The apparatus according to claim 9, including a drive unit connected to at least one of said pressure elements.
- 11. The apparatus according to claim 9, wherein at least one of said pressure elements is movable translationally.
- 12. The apparatus according to claim 11, wherein said pressure elements are plate-shaped pressure elements movable substantially parallel to one another.
- 13. The apparatus according to claim 12, wherein one of said plate-shaped pressure elements is fixed in place and the other of said plate-shaped pressure elements is movable.
- 14. The apparatus according to claim 12, wherein said plateshaped pressure elements are movable in opposite directions.
- 15. The apparatus according to claim 9, wherein at least one of said pressure elements is movable rotationally.
- 16. The apparatus according to claim 15, wherein said at least two pressure elements are at least three cylindrical pressure elements having respective axes and being rotatable about said respective axes.
