The invention relates to vacuum equipment for a fiber web machine. The vacuum equipment includes a frame () arranged to be supported to the fiber web machine. The vacuum equipment also includes a wearing construction () adapted to the frame () and arranged partially open on the surface by means of several openings () for extending a vacuum effect out from within the frame () and further to a fabric () included in the fiber web machine and set in contact with the wearing construction (). The wearing construction () is a plate construction (), the raw material thickness s of which is equal to or smaller than the distance x between the opposite edges () defining the opening (). The invention also relates to a fiber web machine provided with vacuum equipment.

Vacuum equipment for a fiber web machine and a fiber web machine provided with vacuum equipment

A device has two units placed one on top of the other, each unit comprising a first side frame (), a second side frame () spaced from the first side frame, and a band () running between the side frames (). Each unit () has a pressure chamber () attached to the side frames () and positioned in a sealed manner against the inner surface of the band ().

Method and device for changing a fabric in a paper or board machine

A hood () is located above a web forming section (), a press section () and/or a dryer section and includes a ceiling (), a back side wall, and a front side wall (), which includes staggered wall segments (). The wall segments () are adapted to move along rails or similar. The front side wall segments () are adapted to form two or more groups (). A cleaning station () is arranged to automatically clean the side wall segments () as they move past the cleaning station.
