摘要：
Crop processing rolls are provided for operative use in forage harvesters wherein the crop processing rolls are formed with spiraled grooves that are oriented in opposing slopes extending from the opposite ends of the crop processing roll toward the center of the roll. The formation of these spiraled grooves defines teeth from the ridges created with the formation of vertical grooves into the circumferential surface of the crop processing roll. In one configuration, the spiraled grooves meet at the center of the crop processing roll in a V-shaped intersection to provide a chevron shape to the spiraled grooves. In a second configuration, the spiraled grooves do not intersect at the center and form a semi-chevron pattern that does not form a short tooth that the chevron configuration creates at the V-shaped intersection.
