R. Wilken, H.L. Baumgarten and B. Hartmann. Converting challenges to paper and board. In Products of Papermaking, Trans. of the Xth Fund. Res. Symp. Oxford, 1993, (C.F. Baker, ed.), pp 1569–1633, FRC, Manchester, 2018.


The paper converting process forms part of that whole area of engineering known as conversion technology, which applies the rules and procedures acquired in converting to the manufacture of finished products from paper and board.

The resulting conversion techniques consist of a sequence of sub processes in which certain changes in the state of the materials are brought about. The sum of these changes leads from the raw materials paper and board up to the final products.

For the reshaping, separating and connecting processes covered by this report, the specific characteristics and physical principles will be described and the main options of technical realisation discussed. In a number of applied examples, details of the real physical mechanisms encountered in the individual processes will be gone into.

The state of knowledge just set out is required for optimised designing of paper and board articles as well as of the necessary procedures and machinery. It is furthermore an absolute necessity with a view to realising the best possible manufacturing processes whilst taking ecological and work hygiene considerations into account and putting the means of production to economical use
