Abstract: A method of manufacturing a honeycomb body (1) formed by winding around, stacking, and brazing metal flat foils (3) and corrugated foils (4), characterized by comprising the steps of applying adhesive agent to the brazed portions of the flat or corrugated foils corresponding to the connection part (17) at the end part of the honeycomb body and/or a cross sectional connection part (18) inside the honeycomb body apart axially from the end part, winding around the flat foils and corrugated foils to form a honeycomb body shape, bringing the portion of the honeycomb body end face corresponding to the connection part (16) over the entire axial length of the honeycomb body outer peripheral part into contact with the surface of binder liquid to suck the binder into the contact part (5) between the flat foils and the corrugated foils, and spraying wax powder over the honeycomb body to adhere the wax material onto the adhesive agent and binder adhered parts, whereby the equipment cost of a honeycomb body manufacturing device can be reduced and a measure against fire of the honeycomb body can also be taken without causing a defective coating and an increase in coating area found in the coating of adhesive agent with a roll.

Abstract: The invention relates to a method and a device for producing metallic honeycomb bodies for treating the exhaust gas of mobile combustion engines. The components of the honeycomb body are provided with an adhesion promoter prior to a soldering process, whereby said adhesion promoter is applied with precision to predetermined sections in drop form. In particular, the adhesion promoter is preferably applied using ink-jet, bubble-jet or drop-on-demand technology. The invention thus permits the simple production of honeycomb bodies of this type, consisting of sheet metal and with a non-uniform flexibility over the direction of flow and/or in a transverse direction to that of the flow.

Abstract: A superplastically formed, diffusion bonded sandwich structure (30) having integral metal hardpoints (40), made by joining two superplastic metal core sheets (36) together into a core pack (38) by welding or diffusion bonding along a pattern of lines which form junction lines between the core sheets (36) when the pack (38) and metal inserts (40) are interposed between the face sheets (32, 34) and the core (38). All of the sheets in the pack (30) are sealed together around an outside peripheral edge to create a gas tight envelope. The pack (30) is heated to superplastic temperatures in a cavity of a die, and the top and bottom face sheets (32, 34) are diffusion bonded to top and bottom surfaces of the metal inserts (40) by application of heat and pressure from top and bottom inner surfaces of the die cavity. While at superplastic temperatures, the pack (30) is inflated by gas pressure against inside surfaces of a die to form an expanded metal sandwich structure (30) having integral webs (36) and having integral hardpoints (40) formed by the metal inserts (40). After forming, the gas pressure is reduced to near atmospheric, the die is opened and the part (30) is removed from the die.

Abstract: A honeycomb cell structure (10) has a plurality of first strips (16) each formed into a generally zig-zag configuration and placed side by side to form a plurality of rows of cells in a generally honeycomb configuration with nodes (28) between adjacent cells in each row, and a plurality of second strips of brazing foil (12). Each second strip is positioned between a respective pair of adjacent first strips and the first and second strips are secured together at each node such that a brazing foil strip extends across each cell in each row of the honeycomb. The second strips have a series of spaced slits (30) extending transversely from at least one side edge across at least a distance equal to greater than half of the width of the second strip, with at least some of the slits being located within the cells.
