Paper Machine Wire Section At the wet end of the paper machine sits the headbox, which distributes a uniform jet of watery stock. The liquid falls onto the wire or forming fabric. Beneath the wire, foils (short for hydrofoils) remove water and improve fibre uniformity, ensuring that the fibres weave together in a tight mat. The wire passes over suction boxes that vacuum out the water, leaving a soft mat of pulp that forms the paper sheet, also known as the paper web. By now the wire has travelled 30-40 meters. In a couple of seconds, the water content has dropped to 75-80%, and the web has lost its wet sheen.
Paper Machine Press Section The next stage of water removal consists of passing the paper web through a series of nip rollers that squeeze the water out of the pulp mat. This pressure also compresses the fibres so they intertwine to form a dense, smooth sheet. At this stage, the water content has reduced to between 45 and 55%.
Paper Machine Drying Section The paper web now travels through an enclosed space containing a number of steam-heated drying cylinders. They are warmed up to 130ºC using steam heat to ensure that the paper is now 80 to 85% dry. Wet sizing solution is now applied to the paper in order to add a thin layer of starch to the surface. Starch contributes to stiffness and the bonding of the fibres within the sheet of paper. After the sizing is applied, the paper passes through another set of heated drying cylinders. In all, the paper web may travel 400 meters through the dry end. In the process, it will lose roughly 93% of its water.
Paper Machine Finishing Section To give the containerboard a smooth and glossy surface to optimise it for printing, the paper passes through a set of smooth rollers, which can be hard or soft, that press the paper, embossing a smooth face on the paper surface.
Paper Machine Winding Section After completing its 500-metre journey, the paper exits from the paper machine and is automatically wound onto a jumbo reel, which can weigh 50 tonnes and be up to eleven metres wide. The jumbo reel is lifted by crane to a nearby winder, where the paper is unwound and cut into smaller rolls as required by the customer.
