A chip (16) and method for producing wood pulp. First (S1, S2), second (S5, S6) and third (S3, 54) pairs of substantially parallel sides are formed by cutting, cleaving and cutting, respectively. The sides of the first pair of sides (S1, S2) are cut by a first knife (10) so as to be spaced between about 2 to 8 mm. The sides of the third pair of sides (S3, S4) are cut by a second knife (22) so as to be spaced a greater distance apart than the first pair. The sides of the second pair of sides (S5, S6) are cleaved substantially along the grain direction (9) so as to spaced also a greater distance apart than the sides of the first pair (S1, S2). The sides of the third pair of sides (S3, S4) are cut so as to be substantially perpendicular to the sides of the first pair of sides (S1, S2). |
