Process and device for applying glue and brazing material to a metallic catalyst carrier body

摘要

A process for applying glue and brazing material to a honeycomb body includes coating structured metal sheets with adhesive or binder at given positions of zones of the metal sheets to be subsequently coated with brazing material and brazed. Subsequently, the metal sheets are layered or wound into a honeycomb body having a multiplicity of channels for the passage of a fluid. A continuously adhering brazing powder is applied to all of the given positions of the layered or wound body. Excess brazing powder is shaken or blown out of the body. A corresponding device includes a transport path for structured sheets and rotatable sponge-like rollers to be saturated with adhesive or binder. The rollers are disposed laterally alongside and/or above and/or below the transport path. The rollers are rotatable by a transport motion of the sheets or drive mechanisms are provided for rotating the rollers.
