Summary:A stalk roll assembly for header of a combine harvester. The assembly includes first and second stalk rolls spaced laterally with respect to one another and rotating in opposite directions. Each stalk roll includes a frusto-conical nose and a cylindrical body. The cylindrical body includes a plurality of radially extending flutes. The nose includes a pair of helical flights. The plurality of flutes includes at least one cutting flute having a straight edge and a plurality of puncturing flutes with teeth. The stalk rolls are laterally offset a distance that permits the tips of the flutes to laterally overlap and the teeth of the puncturing flutes are longitudinally offset so the tips of the teeth are received between with the valleys of the teeth of the other stalk roll.
