Abstract (en)

[origin: EP0921351A2] The lamellas are stamped-bent parts with a breakthrough and are pushed onto the conduit sections. Starting from the breakthrough (13) one or more distance components (12) are bent into formation, which locate onto the adjacent lemallas and hold them at a distance. The lamellas (10) are made of thin-walled steel plate and have widened formations (14.1, 14.2) in their flame-side areas.
