Abstract: A tubular roll with glide bearings and a method for providing a tubular roll mantle with glide bearings. The roll mantle is supported on a roll axle by hydraulic glide bearing elements which are loaded hydraulically by a pressure medium. The roll is loaded from outside radially in a principal loading direction and the roll mantle is supported on the roll axle by glide bearing elements in the principal loading direction. The loading pressure and lubricant are fed to the glide bearing elements as separated from one another so that the movement of the roll mantle, the speed of movement and the change in speed are regulated by opening, closing and/or throttling the flow in the pressure duct of the loading pressure. The lubricant may be fed to the glide bearing elements irrespective of the loading pressure.

Abstract: A method and arrangement for preventing rewetting of a web in a paper machine. In the method, a web supported by a wire is passed by at least two vacuum boxes/chambers after the last suction roll or equivalent in a web former such that, in the running direction of the web, by means of a first vacuum box/chamber and by means of a second vacuum box/chamber the transport of moisture from the wire back into the web is prevented. In the arrangement at least two vacuum boxes/chambers are arranged after the last suction roll or equivalent in a web former, and the web and wire are arranged to be dewatered by means of a first vacuum box/chamber and the transport of moisture from wire back into the web is prevented by means of a second vacuum box/chamber, the vacuum generated in first vacuum box/chamber being higher than the vacuum generated in the second vacuum box/chamber.

Abstract: A feedback-connected on-line regulation system for a headbox of a paper or board machine. The headbox includes a flow duct for stock suspension or separate flow ducts placed one above the other, each flow duct extending from an inlet header of the headbox into its slice channel.
