摘要

A press for dewatering a fibrous web 24 includes an extended nip 10 provided between a roll 12 and an endless belt 16 which is forced towards the roll by a pressure shoe 14 positioned adjacent thereto for applying pressure to the fibrous web in the nip through the medium of the belt. The belt has a base fabric 20 partially impregnated with polymeric material 22 to provide a first impregnated side 17 which presents a uniform smooth impervious surface for engagement by the pressure shoe 14 and a second side containing voids into which liquid can be transferred from the felt 27 engaged thereby during the passage of the web 24, felts 26, 27 and belt 16 through the nip 10.
