Abstract

In einer dampfbeheizten Walze mit peripheren achsparallelen Bohrungen wird der gleichmäßige Dampfdurchfluß und die störungsfreie Ableitung des sich bildenden Kondensats dadurch herbeigeführt, daß die Ableitungsrohre oder -bohrungen für das Kondensat so ausgebildet werden, daß eine Vermischung von Dampf und Kondensat sichergestellt wird.

Figure 00000001
In a steam-heated roller with peripheral axially parallel bores, the uniform steam flow and the trouble-free discharge of the condensate that is formed is brought about by designing the drainage pipes or bores for the condensate in such a way that mixing of steam and condensate is ensured.
