On an initial pinch roll, the more you raise the lower rolls, the more pressure you add, and the closer the moment of bend gets to the initial pinch rolls (see sidebar illustration). The less pressure the pinch roll exerts and the lower the bending roll is, the farther away the moment of bend is from the initial pinch point.
