Automatic profile measurements
After reading this article you will..
- understand that it is important to have reliable quality data from the produced paper/board as fast as possible and that the profile measurement station can provide it.
- know that although the data that profile measurement station gives is not strictly according to ISO or TAPPI standards, it is very useful in process control and it will show if the product is within specifications or not.
