Fibrous material is passed between a perforated cylinder and a pressing cylinder, the first being provided with means adapted to collect expressed liquid and to remove it preferably from at least one of the ends of the cylinder. The perforated cylinder is of larger diameter and the pressing cylinder is subject to the action of an adjustable pressing means, and is arranged above the perforated cylinder and laterally of the latter. The shaft of the pressing cylinder is displacable in slides and subject to an action tending to bring it towards the perforated cylinder. |
