Paper Roll Characteristics (diameter, width, weight, grammage)

Typically, a paper mill comprises three main stations: Paper machine, Winder station, and Wrapping station. The Paper machine produces paper with particular grammage in gsm (gram per square meter). The typical grammage classes in our paper mill are 48 gsm, 50 gsm, 58 gsm, 60 gsm, 68 gsm, 70 gsm. The Winder station takes a paper spool that is about 6 m width as it’s input and transfers is to customized paper rolls with particular diameter and width. And, the Wrapping station is used for packaging purposes where the white paper roll is packaged with 2 or 3 layers of board paper.After a paper roll enters this station, its properties such as its diameter, width, and weight are measured using physical sensors. On the other hand the paper grammage in gsm or gram per meter square is not measured physically (there is no physical sensor for measuring it in wrapping station) and therefore the wrapping operator have to communicate from time to time with the process operator to get this information. The wrapping operator needs the paper grammage because he must write it manually to the wrapping station HMI application to be printed on the roll label for efficient storage of paper rolls. This dataset contains about 10000 instances, each of them represents the characteristics of one paper roll.
