At least one pair of flutes projecting radially from each roll. The pair of flutes being bilaterally symmetrical and each including a knife edge with a leading surface and a trailing surface forming an acute angle therebetween, whereby the flutes of the adjoining stalk rolls are offset to and overlapping one another.</p>
