摘要:
A sealing arrangement for a roll having a rotationally stationary crosshead extending through a rotatable hollow cylinder which forms an outer working circumference, includes longitudinal and transverse end seals disposed against the inner circumference of the hollow cylinder. The seals form at least one longitudinal chamber in the annular clearance space between the crosshead and hollow cylinder. The longitudinal chamber may be filled with pressure liquid for supporting the hollow cylinder. Each longitudinal seal in the form of a seal strip having a substantially L-shaped transverse cross-section with the shorter leg thereof directed against the inner circumferential surface of the hollow cylinder. The shorter leg includes a contact pressure relief surface facing the inner circumferential surface and spaced therefrom. The relief surface is in fluid communication with the pressure fluid in the longitudinal chamber and oriented so that pressure in the longitudinal chamber exerted on the pressure relief surface reduces the contact pressure between the longitudinal seal and the hollow cylinder.
