Verfahren zur Herstellung eines Wabenkörpers unter Verwendung schon mit Wash-Coat beschichteter Blechfolien

摘要

The aim of the invention is to ensure that end regions (7, 8) of at least partially structured metal sheets (2, 3) which have already been coated with wash-primer remain devoid of wash-primer dust during the production of a honeycomb (1). To this end, the metal sheets (2, 3) coated with wash-primer are treated with a fixing agent at least on one side, preferably on both sides, before being layered, wound and/or folded to form a support matrix (4) of the honeycomb (1), and/or before and/or after being positioned in a casing (6) in the form of said support matrix (4). The inventive method prevents the formation of dust and enables a support matrix (4) to be permanently secured to a casing (6) in an advantageous manner, by preventing harmful deposits, in particular of wash-primer particles which are formed during the production process.
