LL LL OO RR 44 :: BB CC MM II VV AA DD 1) The flat end is the shortest (excellent prebending) thanks to the two central rolls that can take the edge to the precise tangent clamp. 2) Single Pass Sequence The entire shell could be finished in one pass only, including prebending of both edges. ONE only side roll position, one only automatic squaring, and no plate handling required at all. EXCELLENCE IN FORMING 3) Squaring 6) Cones Automatic and instantaneous, plate is squared The 4 roll geometry helps to roll cones, as the against the back roll (a real hydraulic bottom clamping roll can be tilted and clamps back-gauge). the back edge of the plate (at the large diameter LL of the cone), feeding faster its long development.
