Abstract
A press for the dewatering of a fiber web, comprising a roll, a counterpart and and an endless press belt adapted to glide around the counterpart. Into the concave press zone region of the counterpart, a flexible press plate is adapted, anchored to the counterpart at the leading edge of the counterpart, relative to web motion. Beneath the press plate, hydrostatic pressure chambers are provided, separated from each other by means of flexible pressure lines. By individually controlling the pressures of the chambers, the leads and optionally the press plate edges, a desired pressure profile is obtained across the extended pressure zone.
