METHOD, LIFTING DEVICE AND DEVICE FOR REPLACING THE FABRIC IN A RAILWAY TRAINING MACHINE AND APPROPRIATE EDUCATION TRAIN ENGINE

摘要

The invention relates to a method for replacing a fabric in a web forming machine. In this method, the front face (42) on the web forming machine beam (21), wherein between the beam (21) a gap is created for replacing a fabric that forms a closed loop (24). After generating the gap of the gap with a medium lifting device (10) is maintained, wherein in the medium lifting device (10) pressurizable with pressure chambers (30), which are defined by sealing elements (32) are arranged on both sides of the fabric (24) , The sealing elements (32) seal against the tissue (24) when the chambers (30) are pressurized. The invention also relates to a corresponding lifting device, a corresponding device and a corresponding web forming machine.
