Description

Machine for treatment of pulp material.

The invention relates generally to the treatment and refining of pulp material for the production of paper and papler products and in particular to machines "by which the individual fibers in such pulp materials are subjected to the mechanical treatment" which is necessary for the required refining of the pulp _{or the like}

In general, the mechanical treatment may be ^ of subjecting the fibers _B are described essentially as a combined procedure "in which takes place a cutting or severing of the fibers in the transverse direction, as well as a brush or a roughening of the fiber surface. When refining the pulp, in which the retention of the fiber length is important and in which excessive cutting of individual fibers is not desirable? It is worth seeing _s should the mechanical for optimal results
