Patent ID: 6908028

Claim:
A method of manufacturing a honeycomb body formed by winding a flat metal foil and a corrugated metal foil in layers and brazing them at the bonding portion over the full axial length of the honeycomb body outer layers, at a bonding portion which is located at one or both ends of the honeycomb body, and/or at a bonding portion inside the honeycomb body over a cross section which is located away from one or both ends thereof in the axial direction, characterized by: (a) prior to winding the flat and corrugated foils in layers to form the honeycomb body, applying an adhesive to the portions to be brazed of the flat or corrugated foil corresponding to the bonding portion which is located at one or both ends of the honeycomb body and/or the bonding portion inside the honeycomb body over a cross section which is located away from one or both ends thereof in the axial direction; (b) then, winding the flat and corrugated foils in layers to form the honeycomb body; (c) then, after winding the flat and corrugated foils in layers to form the honeycomb body, depositing a liquid adhesive at the portion of the honeycomb body corresponding to the bonding portion over the full axial length of the honeycomb body outer layers by making the portion of one or both end faces of the honeycomb body corresponding to the bonding portion over the full axial length of the honeycomb body outer layers contact the surface of the liquid adhesive and having the adhesive sucked up along contact lines of the flat and corrugated foils; and (d) then, feeding a brazing filler metal in powder to the honeycomb body so as to have it deposited at the portions where the adhesives have been applied or deposited.
