The retention of a body in a housing through which gas flows is indicated. This retention consists of a metallic network or mesh which has arrow-shaped impressions on both sides and sheaths the body in one or more layers. The angle of the arrow is preferably 70 DEG , and the network ends can be folded inwards at both ends so that double the number of layers of the retaining network are produced in the edge region of the body which is to be retained. |
