In the tissue machines, there are four main types of forming sections - a crescent former, twin-wire, suction breast roll, and Fourdrinier. The most common forming section for tissue grades, nowadays is the crescent former, as it provides a superior ability to run at high speeds. The twin-wire promotes efficient dewatering and good control of fiber orientation. The dewatering is controlled by suction in a suction breast roll former so that the water is drained from the space between the wire and the top of the headbox. In Fourdrinier, dewatering happens in a single direction through the web by suction and gravity and is limited in speed.

To increase the consistency to the range of 15% to 25%, vacuum systems, such as suction boxes or suction rolls, are usually used. The creping process is a very important step for the production of tissue products with higher bulk, absorbency, softness, and stretch.

To decrease limitations in tissue machine speed caused by variable crepe in the TAD process at higher speeds, UCTAD was developed. Similarly, DRC was developed to produce a product that is similar to a two-ply product from a single tissue sheet. In the early 2000s, ATMOS was developed. The goal of this energy-efficient process was to use mechanical means to dewater the sheet to 34% to 38%, before contact with Yankee. To overcome some of the limitations of ATMOS, NTT was designed by pressing at even higher pressures before transferring to Yankee. Before transferring to the Yankee, initial production has indicated the ability to achieve 45% consistency, which has reduced the Yankee Hood drying load as compared to ATMOS.
