Method and apparatus for the end-surface connection of a carrier matrix of a honeycomb body by a joining technique

Abstract

A method and an apparatus produce a connection of at least at one end surface of a carrier matrix of a honeycomb body, in particular a catalyst carrier body, by a joining technique. The matrix is disposed in a tubular jacket and is laminated and/or wound from at least partially structured sheet metal foils or layers. The end surface of the honeycomb body is at least partially heated up with the aid of a surface inductor having induction coils. The induction coils are disposed in such a way that interconnections of the sheet metal foils or layers are established at least at locations, in particular at spots. Such connecting spots are preferably established variably with regard to their extent over the end surface. The surface inductor is variable with regard to the production of connecting locations and/or connecting spots, that is with regard to effective regions. The invention is suitable in particular for connections made by joining techniques such as brazing or sintering and can be applied while the process of producing catalyst carrier bodies is in progress.
