<p>A papermaker's pressure belt for extended nip presses, which comprises a belt base formed of a strong woven fabric having high dimensional stability, a squeezing layer to be in contact with a wet fibrous web on an extended nip press, having a large void volume and formed of a compressible elastic and porous or cellular material, such as fibrous batt, sponge or a foam resin, and formed on one side of the belt base, and an impermeable layer impermeable to oil, formed on the other side of the belt base. The squeezing layer facilitates the separation of the fibrous web from the pressure belt, while the impermeable layer inhibits the permeation of the lubricant applied to the acting surface of the pressure shoe of the extended nip press through the pressure belt.</p> |
