The individual work roll drives of the Butech Bliss leveler turn at exactly the speed dictated by their plunge setting. In fact, the Butech Bliss leveler controls the torque of each work roll individually, so that the rolls needing the least amount of torque (exit) actually help those requiring the highest torque (entry) by pulling tension in the strip. Butech Bliss’ hydraulically-operated roller levelers do not require an expensive non-standard distribution box. Instead, Butech Bliss roller levelers use common, off-the-shelf lower horsepower motors and individual reducers. This exclusive feature provides inter-roll tension, greater energy efficiency and uptime redundancy while eliminating strip marking caused by slippage.
The inherent advantage of a Butech Bliss hydraulic leveler is the ability to provide superior shape correction through the use of a closed-loop hydraulic servo system that automatically compensates for machine deflection. There are no wedges to be manually adjusted and manipulated.
