Process and apparatus for producing a metallic honeycomb body
First Claim
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.

Abstract
A process for producing a metallic honeycomb body includes winding, laminating or intertwining at least one at least partly structured layer of sheet metal to form a matrix placed in a tubular jacket. At least the tubular jacket is elastically deformed by successively exerting a substantially linearly and radially inwardly directed force on the peripheral surface of the tubular jacket, as seen in circumferential direction of the tubular jacket. An apparatus for producing a metallic honeycomb body includes at least two mutually movable and variably spaced apart pressure elements for receiving the honeycomb body therebetween and bringing the 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.

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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
