Abstract：

The principles of a new proposed stretching machine named flexible-roller stretching machine were introduced briefly. The stretching process was stimulated with commercial FEM software. And three different loading paths were designed and studied, and a contrast was made among them. The results show that it will have more advantages in crack preventing when the rollers are adjusted into a downward protruding arc shape in the forming process than that into a straight line. And if the radius of the arc is smaller, the better effect in preventing cracks can be obtained.
