Our patented eDrive® technology employs tension leveling techniques for gauges .010" to 1". With today's laser cutting machines in widespread use, erasing the footprint of internal stresses in flattened metals has become more important than ever. The eDrive® was developed to equalize these internal stresses while delivering superior flatness.
Bradbury roller levelers are in service around the world. Our customers come back again and again for the ease of operation, the repeatability, and the quality of the final product. Call us and let us show you this outstanding technology.
The patented Bradbury eDrive® system was developed after discovering the mismatch of roll speeds as material makes its way through a leveler. This phenomenon was noticed when torque limiters on the drive shafts of the exit rolls were showing excessive wear as compared to the entry shafts. Further testing revealed that material was actually being forced through levelers from the front. With all leveler rolls of equal diameter and geared the same, material was “bunching up” internally, greatly reducing the stretching process required to equalize material shape. The plunge of the entry rolls has everything to do with yielding the material to a plastic state. Yet when the plunge was increased, the bunching would worsen, and horsepower consumption would increase with little material improvement being gained.
