ABSTRACT:
A conditioner roll tread pattern comprising a plurality of equally circumferentially spaced ribs separated by grooves extending across the axial length of the conditioner roll. The ribs are angled relative to the axial centerline, either with a fixed positive
egative angle or a continuously varying angle alternating between positive and negative extremes. The conditioner roll is configured to work in conjunction with a paralley disposed roll of similar tread pattern configuration, reversed end-for-end so that the ribs of one roll intermesh with the grooves of the adjacent roll. The location of the transition points at which the angle reverses along the axial length are coordinated with the transverse locations of converging and diverging crop flows being discharged from a forwardly disposed rotary disc cutterbar in a manner that results in a crop mat having more uniform thickness being discharged from the conditioner.
