Automatic profile measurements Introduction The profile measurement stations perform different measurements from the paper or board sample automatically. They can measure sheet-type samples but usually the sample is a cross-profile of the jumbo reel. Sometimes, machine-directional profiles are measured to find out if there are machine-directional deviations in certain paper properties. They are fully automated

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.
