Abstract
The method serves for the altering of suspended paper fibers or pulp fibers, in particular to increase the strength of the paper made from these fibers. Two refining surfaces are pressed toward one another and moved such that a relative speed prevails between the refining surfaces and the pulp in the refining zone which is as low as possible. The method can be carried out particularly easily with refining bodies which carry a refining surface and which are rolled off on the inner side of a refining drum carrying the refining surface.
