The device holds the ends of insulating mats against the inside walls of air ducts at the ends of the ducts where frame pieces form external glands on the ducts. The frame piece has a stay which rests on the outside of the air duct wall and a stay which rests on the inside of the air duct wall. The inner stay is bent back on itself and with multiple bends forms a longitudinally opening pocket which has a transverse-running catch strip with a v-shaped groove form at its free end, pointing towards the inner stay. A cross-connecting spot weld connects the o...
In a device for holding the edge of inner insulating mats which extend transversely to the longitudinal direction of an air-conducting duct in the area of a metal frame piece which forms a prefabricated gland, in which the frame piece has a stay which runs inside the wall of the air-conducting duct and lies against the latter, a stay which rests on the outside of the duct wall and a connection means which, in the assembled state, connects the stay of the frame piece resting on the outside of the duct wall, the duct wall and the inner stay of the frame pi...
