Design: A screw press consists of a large screw mechanism enclosed within a frame. The screw is usually cylindrical or conical in shape and is rotated by a handle or a mechanical means. Operation: The wet paper sheets are placed between layers of absorbent material such as felt or wool to help absorb the water. Then, the stack of paper and absorbent material is placed between the plates of the screw press. Application of Pressure: As the screw is turned, it applies pressure to the stack of paper and absorbent material. This pressure squeezes out excess water from the paper sheets, helping to consolidate the fibers and create a denser, stronger sheet of paper. Release: Once the pressing is complete, the screw is reversed, and the pressure is released. The pressed paper sheets are then removed from the press and transferred to a drying area.
