b'control at the edges of the cylinder (via an independent pressure regulator and depressors). Fibre build-up at the edges are therefore perfectly removed, maintaining the right blade load along the entire paper width. But performance must always go hand in hand with safety; for that reason, the ELV system has been designed to allow for edge tube depressors to be adjusted whilst the machine is runningwith no need for manual fine-tuning with a screw, thus preventing operator injury and guaranteeing extra safety.Figure 5. OraCrepe 30 in production.Removing the need for stoppages and operator intervention directly translates into added value for the whole tissue making process.Similarly, the extractor device, often supplied along with the doctoring system, is very helpful in allowing the operator to replace the blade in a safer way, as it pulls the blade out as much as the operator may need in order to safely remove it.
