Description

unmittelbar gegenüberliegender Rhomboide gleichschenklige Trapezflächen entstehen. Hierdurch wird eine der Doppelkante 18 in Fig. 1 entsprechende Doppelkante vermieden.Immediately opposite rhomboids form isosceles trapezoidal surfaces. This will one of the double edge 18 in Fig. 1 corresponding double edge avoided.

Werden vier rechteckige Blechteile auf die beschriebene Art in vier parallel verlaufenden Verbindungsbereichen zusammengefügt, so entsteht ein Balg, der sich gut eignet zum Umkleiden von Wandberohrungen von Dampferzeugerbrennkammern oder zum Verbinden von Heißgaskanalabschnitten.Are four rectangular sheet metal parts in the manner described in four parallel connecting areas put together, the result is a bellows that is well suited for cladding wall tubing of steam generator combustion chambers or for connecting hot gas duct sections.
