ABSTRACT:
A wood chip stream capable of being selectively delaminated is produced by separating a mill-wood chip stream into respective first and second fractions on the basis of wood chip thickness. The first fraction consisting of wood chips having a predetermined thickness, is then pulped by conventional techniques. The wood chips in the second fraction are reduced to said predetermined thickness and are then selectively delaminated by compression means. After being subjected to selective delamination, the delaminated chips are pulped by conventional techniques. Accordingly, a high yield, uniform wood pulp having reduced pulp screen rejects is produced.
