A paper machine (or paper-making machine) is an industrial machine which is used in the pulp and paper industry to create paper in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven mesh to create a continuous paper web by filtering out the fibres held ...
This machine produces a continuous roll of paper rather than individual sheets. These machines are large. Some produce paper 150 meters in length and 10 meters wide. They can produce paper at a rate of 100 km/h.
In the manufacturing process, pulp is introduced into a paper machine where it is shaped into a paper web and water is extracted through pressing and drying stages. Pressing involves removing water from the sheet by applying force. This process employs a specialized type of felt, distinct from traditional felt, to absorb the water.
Large Fourdrinier-style paper-making machine. A row of heated drums dry out the paper, which enters the machine as wet pulp. Large rolls are usually sliced into a number of thin rolls, which can feed continuous presses (e.g. newspapers) or be cut into separate sheets. Sealy Fourdrinier (9 October 1773 – 1847) was an English paper-making ...
The United States is one of the biggest paper consumers in the world. Between 1990 and 2002, paper consumption in the United States increased from 84.9 million tons to 97.3 million tons. In 2006, there were approximately 450 paper mills in the United States, accounting for $68 billion. [1]
In 1965 a paper machine was being installed at the Jackson, Alabama site for a cost of $11 million. It could produce up to 250 tons of paper per day. [ 20 ] In spite of numerous strikes at its mills, Allied profits were $114,494 and $806, 304 in 1964 and 1965 respectively.
Bryan Donkin was the key engineer in the development. The first commercial machine, crude as it was, was installed at Frogmore, Hertfordshire in 1804 and this was followed by another experiment and then a better version at Two Waters nearby in 1805. This machine cost £4204. This early machine made paper was of course rag based.
1896 Beloit Iron Works builds a new foundry, machine shops and offices on the-west side of Rock River near the original site of the Merrill plant. 1897 Shipped first off shore paper machine to Japan. 1900 Shipped two paper machines to China. 1900 Beloit builds cylinder machine to operate at 75 FPM and fourdrinier machines operating 400 to 500 FPM.
