a specific distance corresponding to the quantity or amount of solder needed i e the foil is pressed into the wound up honeycomb element to such an extent that the solder will remain during the soldering operation within the individual honeycombs the pressing in of the solder takes place with the aid of pressing devices 56 and or 57 whereby layered or coated zones 59 39 and 59 34 will be produced the advantage of this variant consists in that an exactly uniform amount of solder is utilized according to another variant of the inventive method or process which has not been illustrated herein in an electric arc compressed air process an auxiliary material for example nial wire 95 ni 5 al in the form of a wire is melted down by means of an electric arc and sprayed by means of a compressed air jet onto the honeycomb element on the front side thereof the individual particles having been sprayed on will weld together and interlink on the front side of the bearing points of the individual bands 1 and or 2 as a consequence of the exact reaction of aluminum in the auxiliary material and of the base material a firm adhesion of the sprayed coating is produced during the spraying the flame spraying gun may be moved in an undulating fashion over the surface of the matrix and or the matrix may be guided past the flame spraying jet the wire weight to be sprayed on must.
