PAPER FROM WOOD-PULP 



Illustration of the beating machines, in which the wood-pulp (or similar fibrous material like esparto grass) is broken up, and, with 

 the addition of water, reduced to a state like thin milk. This is then refined to remove foreign matter and lumps. 



The liquid pulp is then pumped into a machine and passed over a wire-mesh, which moves continuously forwards and also from 

 side to side. The liquid drains through and the fibrous materials are left, the complex movement disposing the fibres so that they inter- 

 lace. A suction box over which the wire-mesh then passes removes any remaining water from the interwoven fibrous sheet, which has 

 now become paper. To complete the process, the paper is carried on a blanket over a series of heated rollers, and thoroughly dried.

 use on the printing machine. A reel often contains more than five miles of paper.
