Claims15
A method of assembling cutting blades on a blade shaft comprising placing first and second blades on the blade shaft so that respective reference elements on the first and second blades engage a complementary reference element on the blade shaft and wherein a first flow opening on the first blade has a first geometry and first cross-sectional area in the blade and first radial position and first arcuate position relative to the reference element on the first blade and a second flow opening on the second blade has a second geometry and second cross-sectional area in the blade and second radial position and second arcuate position relative to the reference element on the second blade, and wherein at least one of the second geometry, cross-sectional area, radial position and arcuate position is different from at least one of the first geometry, first cross-sectional area, first radial position and the first arcuate position.
A method of assembling a cutting blade assembly having a blade shaft and first, second and third blade cores having respective blade shaft openings through which the blade shaft extends, wherein each of the first, second and third blade cores further include respective surfaces configured to engage a reference element on the blade shaft to position each of the first, second and third blade cores circumferentially on the blade shaft, the method comprising placing each of the first, second and third blade cores having respective first, second and third flow walls defining first, second and third flow openings in such a way as to define a first flow passageway extending other than parallel to the blade shaft, and with respective fourth, fifth and sixth flow walls in the first, second and third blade cores defining respective fourth, fifth and sixth flow openings defining a second flow passageway extending other than parallel to the blade shaft.
