HIGH TENSION PERMEABLE BELT FOR AN ATMOS SYSTEM AND PRESS SECTION OF A PAPER MACHINE USING THE PERMEABLE BELT

摘要

A permeable belt, a belt press including a roll having an exterior surface and the permeable belt, and a method of drying or pressing a web with the permeable belt. The permeable belt has a paper web facing side and is guided over a support surface. The permeable belt can have a tension of between approximately 20 kN/m and approximately 100 KN/m, a permeability value of between approximately 100 cfm and approximately 1200 cfm, a surface contact area of the paper web side that being between approximately 0.5% and approximately 90% when not under tension, and an open area of between approximately 1.0% and approximately 85%. The permeable belt provides enhanced dewatering of the paper weft by use of the permeable belt as a pressing element.
