摘要
The invention relates to a method for replacing a fabric in a web forming machine. In the method, the front side (42) of the web forming machine comprises beams (21) between which beams (21) a gap is created for replacing a fabric forming a closed loop (24). After creating the gap, the gap is maintained with a medium lifting device (10), in which medium lifting device (10) pressurizable chambers (30) defined by sealing elements (32) are arranged on both sides of the fabric (24). The sealing elements (32) are sealed against the fabric (24) when pressurizing the chambers (30). The invention also relates to a corresponding lifting device, arrangement, and web forming machine.
