Online Density Measurement System for Winders
To make the paper rolls of high quality is a good density measurement system is necessary.
The Density Measurement System has an extremely advanced pulse counter made in programmable logic circuits.
The pulse counter is done with a specially developed algorithms to provides an extreme resolution and 60 layers of paper after reel change are the density measuring working (see Figure 1).
Thickness and density measurement is updated every three layers of paper.
