Abstract
An apparatus, method and band for forming and/or dewatering a fibrous web, in which the web or a pulp suspension layer forming the same is conveyed and supported through a significant portion of its run in a paper machine by a specific processing band, while liquid such as water is simultaneously removed therefrom by hydraulically contacting the same with liquid present under vacuum or underpressure within the processing band, through a finely porous, liquid-suction surface on the band that is saturated with liquid.
