Kind Code:
Y2
Abstract:
In a roll for pressure treating webs of material comprising a stationary core which is surrounded by a rotatable hollow cylinder spaced from the core, and in which there are provided, between the core and the hollow cylinder, longitudinal seals and end seals which seal off a longitudinal chamber which extends between the core and the hollow cylinder on the side of the working gap and is filled with a pressure liquid, with discharge canals provided in the core for discharging leakage liquid from the space between the core and the hollow cylinder which remains between the core and the hollow cylinder on the side facing away from the working gap, an improved sealing arrangement, which includes a strip which extends along the hollow cylinder over the length of the longitudinal chamber following in the direction of rotation, the seal projecting at an angle from the core toward the longitudinal seal up to the inner circumference of the hollow cylinder and discharge canals opening in the region between the point where the strip is secured to the core and the longitudinal seal, is provided to reduce friction.
