Abstract
A method of producing a honeycomb body including a stack of structured metal sheets disposed in layers at least partially spaced apart from each other defining a multiplicity of channels through which gases can flow, the stack having ends twisted in mutually opposite directions about at least two fixation points, and a jacket tube surrounding the sheets and being formed of at least one segment, the sheets having ends joined with the jacket tube.
Claims13
Method for producing a honeycomb body, which comprises:
- (a) layering a given number of structured metal sheets with ends into a stack with ends;
- (b) grasping fixation points at the stack with at least one fork-type tool and twisting the ends of the stack in opposite directions with the at least one fork-type tool while bending over the ends of the stack;
- (c) providing the twisted stack with a jacket tube;
- and
- (d) joining the ends of the structured sheets to the jacket tube.
Method for producing a honeycomb body according to claim 24, which comprises performing the step of joining the ends of the structured sheets to the jacket tube with a brazed seam extending in the circumferential direction around the jacket tube.
