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.
