Leveler Takes a Deep-Roll Plunge

Braner/Loopco, Schiller Park, IL, introduces the Torquemaster precision roller leveler, promising improved flatness and springback memory stability compared to conventional levelers. Noted is its ability to plunge work rolls deeper into the material and to work the strip harder than is feasible with conventional levelers, where work rolls are geared together and driven by one or two motors. This conventional design forces the rolls to rotate at the same speed, leading to wind-up torque that can cause premature drive-train failure.

Deep roll plunge with the Torquemaster increases strip elongation, say company officials, essential in stabilizing springback memory and correcting strip shape. Each of the work rolls has its own motor and gear box, so they can individually synchronize with strip speed.
