Abstract

The holding of a catalytically-active monolith in a housing in the exhaust line of a liquid fuel-operated motor is done by a holder made of a knitting wrapped about a catalyst monolith. The knitting includes a segment with an undeformed thread area, where one or more sealing strips are accommodated, so that the holding qualities are improved with good prevention of a by-passing gas flow about the monolith, and the sealing strip is protected against abrasion and destruction and is securely retained in its position.
