Abstract (en)

[origin: EP0943729A2] The sealing element (14) is pressed against the moving surface (12) by a loading device, e.g. a flexible hose (18) expanded by hydraulic pressure. An unloading device, e.g. a pneumatically inflated hose (20) acts in the opposite direction. By controlling the pressures in the hoses (18,20) the sealing gap (40) can be controlled at the desired value to reduce wear. When the paper machine is started up only the loading device (18) is activated. Once the machine is up to speed the unloading device (20) comes into action to reduce the load to the desired value. Pairs of loading elements can be inflated differentially to give a tapered sealing gap (40).
