Abstract: The invention relates to a device for dewatering and defibrating ligno-cellulose material using a screw. It is primarily characterized by a defibrating element (9) directly adjoining the body (2') of a first screw.

Abstract: A distributor gear assembly includes a housing having a driving shaft and first and second distributing shafts rotatably mounted therein such that the axes of the three shafts are disposed in a common plane. An annular internal gear wheel is rotatably mounted in the housing with the three shafts passing through the annular internal gear wheel. Each of the three shafts has a gear mounted thereon with the gear on the first distributing shaft being axially offset relative to the gear on the second distributing shaft, the gear on the driving shaft meshing with the annular internal gear wheel and with the gear on the first distributing shaft and the gear on the second distributing shaft also meshing with the annular internal gear wheel.
