Application No. 09/839,766
a) providing at least one metal sheet with corrugations having
crests;
b) defining first zones on the metal sheet to be continuous along
some entire crests and defining second zones on at least one
narrow edge zone of the metal sheet;
c) applying adhesive material only to the crests within the zones
and leaving all other locations of the metal sheet substantially
free of adhesive material;
d) subsequently incorporating the metal sheet in a honeycomb
body, the adhesive material being naturally displaced to further
positions adjacent the connecting positions;
e) apply brazing powder to adhere to the adhesive material at the
further positions of the honeycomb body; and
f) removing any excess brazing powder from the body and brazing
the honeycomb body for forming a metallic catalyst carrier body.

Appellant's claimed invention is directed to a process for
forming a metallic catalyst carrier body formed by bonding a
corrugated metal sheet with another section of sheet-metal. The
method entails applying adhesive material along the entire crests
of only some of the corrugated crests, and also applying adhesive
