Abstract
Apparatus for pressing liquid from a liquid containing material is disclosed including a pair of juxtaposed rotary rolls forming a nip, at least one of the rolls being liquid permeable, that roll including an abduction surface extending laterally across the roll so that a portion of the liquid stream pressed out form the liquid containing material passing through the nip runs along the abduction surface, a liquid collector for collecting that portion of pressed out liquid extending laterally across the roll and including a liquid inlet for the pressed out liquid stream, and a return flow protector for preventing the pressed out liquid stream from rewetting the reduced liquid material formed in the nip.
