Abstract

Dispositivo di tenuta tra l'estremità di alimentazione in entrata di un cilindro rotante e l'estremità di scarico di uno scivolo fisso, in cui l'estremità di scarico dello scivolo fisso è accolta all'interno di un'apertura dell'estremità di alimentazione in entrata del cilindro rotante. Il dispositivo di tenuta comprende un materiale flessibile dalla configurazione anulare, con il diametro interno dell'anello che è in pratica eguale al perimetro esterno dell'estremità di scarico dello scivolo fisso, il materiale flessibile essendo fissato all'estremità di scarico del cilindro e circondando la stessa. Un dispositivo di compressione è fissato all'estremità di scarico dello scivolo fisso, il dispositivo di compressione comprendendo un'estremità che si estende verso l'esterno che è in relazione di compressione rispetto al perimetro esterno del materiale flessibile, per spingere il materiale flessibile contro una parete interna estesa trasversalmente dell'estremità di alimentazione in entrata del cilindro rotante.
