摘要

PURPOSE: A double drier of a paper machine is provided to increase an amount and a speed of drying paper by installing the double drier including an infinity drier, canvas, and a hot air drier. CONSTITUTION: A double drier of a paper machine comprises a first drying group(100) and a second drying group(200). A big infinity dryer(10) is installed on a lower end main frame between the first and second drying groups. A canvas(20) rotates an outer periphery of the infinity drier. The canvas adheres to the infinity drier by a touch roll(30). Moisture contained in the canvas is absorbed while the canvas passes a vacuum roll(40) installed at a lower end of the second drying group. A hot air drier(50) is installed at one side outside of the canvas that rotates the periphery of the infinity drier.
