Paper Machines have an extra smoothing process called a calender, which is added to the dryer screen. The calender consists of several rollers arranged vertically one upon the other. By running the almost dry paper web between the rollers under high pressure, the paper is compacted and smooth. The finished paper web is wound up on a steel shaft (Reel). The Paper now contains 5-8% moisture content.
The paper now has all the characteristics required for its end-use, but must be cut to the size required by the customer.
The jumbo reels are transported to a finishing department, where they are cut into narrower reels by a slitter / rewinder.
