Abstract: The present invention relates to a continuous press constituted by a central wheel jointly rotatable with a shaft driven at low speed, and the rim is provided with bearing and guiding means for a movable external crown whose internal diameter is greater than the external diameter of the rim, constituting in association a rotary assembly of two cylinders internally substantially tangent to one another, at least one of the two cylinders being perforated, the external crown being applied radially against the rim of the internal wheel by means of a device bearing upon the wheel or its shaft, constituted essentially by two spools rotating freely about their shafts and externally tangent to the external crown and by a system of production and transmission of the tightening effort, not driven in rotation.
