The Yankee dryers paper machie is really a large can heated to a very high temperature, dry steam inside and air heated on the outside. It replaced many dryers section fabric with a single, larger one, usually 300 inches wide and about 10 feet in diameter. It also can cutting down the length of the paper machine by 10-20 feet and dry the sheet in those ten feet. 

There are two mainly kinds of drying systems: a hot surface (like the Yankee dryer) and a system using dry steam or hot air that actually blows through the wire. Because a thicker sheet can be dried in much less time using this process,the blow through drying fabric enabled tissue products like Charmin, . 

Usually, a series of cylinders apply several layers of stock, creating a multi-layered paper sheet,this device enables the creation of multi-layered paperboard. Once all the necessary layers are applied, the felt rotates to the top side of the drying fabric and enters the pressure roll part of the machine. The multiple layers could not be applied normally, from the top of the wire, because gravity would begin to dismantle the lower layers during paper making.
