◆ Aim and purpose of the tissue machine
The ultimate aim of any tissue paper machine is to produce a lightweight sheet of paper that is soft, absorbent and strong enough to fulfill the functions needed, and which can then be converted into finished products which will be accepted by consumers and buyers in the marketplace. These products may include items such as bathroom tissue, paper kitchen towels, facial tissue, handkerchiefs, commercial and industrial wipers and sometimes even items such as medical disposable wraps and garmets.
To create this sheet, tissue machines thus designed to evenly distribute a suspension of wood fibers in water into a very thin layer, and then to remove most of the water. The suspension of wood fibers and water, called ‘stock’, usually has an initial composition of around 99.5% water and 0.5% solids, mostly fibers. Finished basis weights of tissue are typically in the range of 13-25 grams/square meter (gsm).
The sheet-forming process involves first draining off as much of the water as possible in the forming section, then pressing it out between rolls in the press section, and finally removing the remaining water by heat and drying through the use of thermal energy. Drying is usually done via direct contact of the sheet on the hot Yankee dryer surface, as well as by impinging hot air onto the sheet in the Yankee hood
