Transverse end seal for a flexure-controllable roll

Abstract From the Canadian patent

In a hydraulically supported roll including a rotatable hollow cylinder and a statopmaru crosshead transverse end seals are provided to seal the annular clearance space formed between the crosshead and the inner circumference of the hollow cylinder. Each transverse end seal includes a slide ring having A chamber located on the first surface of the slide ring abutting a counter-ring. The chamber provides hydraulic relief. Radially outside of the chamber a narrow groove is provided which communicates with the low-pressure side of the slide ring via a channel. The channel discharges hydraulic fluid flowing to the first surface of the slide ring as a result of the high pressure in the clearance …
