摘要： The invention relates to a beam structure for a web forming machine. The beam structure is arranged to be supported by its end components (10) on the web forming machine. Th beam structure includes a casing structure (15) of a thin-sheet material, inside which a stiffener structure (30) is arranged. In addition, the casing structure (15) and the stiffener structure (30) are secured to each other to create a load-bearing beam structure.

摘要： A device for cutting a fibrous web by a pressurized medium, comprising: - a beam that is arranged essentially transversally to the direction of travel of the fibrous web; - a carriage that is adapted to move, to which a nozzle for cutting the fibrous web is attached; - a line (4) for conveying the pressurized medium to the nozzle the first end of the line (4) being adapted to be connected to a pressure feed and the second end of the line (4) being adapted to move in connection with the carriage. The device is characterised in further comprising a guide trough (13) for forming the guide of the line (4), that the line (4) is adapted to move in the guide trough as an essentially U-shape loop, when the distance between the first end and the second end changes according to the position of the carriage, and that the movement of the line is arranged to be provided by the movement of the carriage fitted in a linear module.
