Removing Water

Removing water is the next important stage. For this the pulp is passed through a rapidly moving wire mesh called fourdriner or some time called machine wire. The objective is to recover 93 to 95% of the water in the finished paper.

As the paper flows along the wire mesh and water is drained along the way, a dandy roller near the end helps to smooth out the paper. The dandy roller will improve the formation of the paper web by application of pressure. When the paper reaches the end of the wire mesh it is transferred to a felt blanket which conveys it through many steam heated driers to remove the excess moisture. In the process the paper gets some glaze like coating also.


Then it is made to pass through a series of calendar stacks. The calendars are series of polished iron rollers stacked one on top of the other, through which the finished paper will pass to smoothen down.

The next step is rewinding on a metal or fibre core pope reel. The last stages after this are sheeting, packing & testing.
