It consistsof four collared or grooved rolls, two placedside by side (separated by a space which isadjustable), and two one above the other,directly above the line between the twoside rolls. The axes of the upper and low-er rolls are parallel; the axes of the two siderolls are parallel in their vertical planes,but their horizontal planes cross at a slight angle, one being raised above the other at one end, thesecond being raised above the first at the other end. The two side rolls revolve in one bar to be rolled is passed into the quadrangular-shaped space between the faces of four rolls,and the surfaces of the side rolls touching it and rotating in contrary directions cause it to
