Process for manufacturing a honeycomb body, in particular a catalyst carrier body, formed of a plurality of entwined bundles of sheet metal
First Claim
1. A process for manufacturing a honeycomb body having a multiplicity of metal sheets defining a multiplicity of channels through which a fluid can flow, which comprises:
- (a) stacking metal sheets into at least three separate bundles of metal sheets having ends;
(b) moving the bundles toward a central region and bending each bundle about a respective one of at least three bending lines defining a bend in each bundle;
(c) entwining the ends of the bundles in the same direction; and
(d) encasing the entwined bundles in a prefabricated jacket.

Abstract
A process for manufacturing a honeycomb body having a multiplicity of at least partly structured metal sheets defining a multiplicity of channels through which a fluid can flow includes stacking at least partly structured metal sheets into a plurality of bundles of metal sheets having ends. Each bundle is folded about a respective bending line defining a folded edge of each bundle and the folded edges are simultaneously or subsequently moved toward a central region. The ends of the folded bundles are entwined in the same direction, such as by rotating the central region and contracting a form surrounding the bundles. The entwined bundles are encased in a prefabricated jacket by pushing the entwined bundles into the prefabricated jacket or surrounding the entwined bundles with the prefabricated jacket.
