Abstract (en)

[origin: EP0930478A2] The exchanger has water-bearing pipes and a lamella packet through which the pipes pass. The lamellas have cantilevers which rest on neighboring lamellas, whereby outwardly-pressed naps (22) are provided on the periphery of the cantilevers (14) which lie on neighboring lamellas outside of the rounded punched-out regions. The distal edge surfaces (26) of the crown regions (24) lying on the neighboring lamellas are positioned parallel to the plane of the lamella by a calibrating procedure.
