The increased use of recycled waste paper and the reduced basic
weight of paper have induced the rapid increase in the speed of
paper and board machines. The current design speed of paper machines
reaches 2000 m/min and that of board machines reaches 1800 m/min.
Numerous innovative technologies have been developed as a result
of the challenges to reduce the basic weight and increase the machine
speed. Because of the above technologies, the current design of
paper and board machines has become quite similar. In addition,
peripheral technologies, such as feed stock optimization, online
self-diagnosis of machines, have rapidly advanced to improve the
overall efficiency of the paper mill process. This paper reports
the new developments of the latest paper machines in individual
sections.
