Rebound behaviour of the felt

In paper production process, a felt is used to transport the paper web from the screen station to the pressing station and it also removes moisture residues from the paper. For determining the quality of a paper, the wear and the rebound behaviour of the felt are the deciding factors. Hence, it is important to monitor the wear at the guide roller consistently to ensure a fine production of paper. 

Bestech Australia has optoNCDT Laser-optical position measuring system suitable for use in this situation. Two sensors are used to perform the measurement and the effective thickness measurement of the felt is generated as a result. On finding a value falling below the specified limits, the production is stopped and the felt is replaced. These sensors come with a protective housing in order to survive ambient environment and operating conditions.
