water from the paper by sucking it out of suspension. Multi-layer paper machines and paper board machines include additional forming sections (one forming section for each layer of paper). Forming section drives have a high friction load due to the suction (normal forces) of the water through the wire mesh. This results in a high

Paper mill process, piping and piping guide: PAPER MAKING

Fourdrinier was created by the Fourdrinier brothers at the beginning of the 19th century. The machine consists of a flat, horizontal wire that runs through a series of foils and dewatering devices. The Fourdrinier machine illustrated in Figure is suitable for a wide range of paper grades. In many cases these machines have been modified to

The dryer section of a paper machine removes between 1.1 and 1.3 kg of water per kg of paper compared to 200 kg and 2.6 kg in the forming and press sections respectively. It is significantly more expensive to remove this water than for any other section of the machine (Reese, 1988). The relative costs of dewatering are: forming section 10%; press

In 1806 Henry Fourdrinier had obtained patent No. 2951 for a method of making a machine for manufacturing paper of an indefinite length, laid and wove, with separate moulds. However, Fourdrinier's patent for the endless chain-mould machine did not accompany his specification with drawings and did not describe the machine in much detail.

Hydrofoils or "Foils"

On a Fourdrinier paper machine the foils are placed under the forming fabric. Their shape is designed to create suction as the foil and wet web pass over the surface. Hydrofoils also create a brief pressure pulse as the fabric passes over the leading edge. The alternating pressure and vacuum of a series of hydrofoils tends to move fibers around ...
