Featured Item: Evolution of the Bradbury eDrive® Leveling System
Evolving through research, development, and testing, the Bradbury eDrive® leveling system offers the industry the most up to date leveling technology available.
eDrive® (US patent#8893537) - Bradbury eDrive® was developed after discovering the mismatch of roll speeds as material makes its way through the leveler. The eDrive® equalizes internal stresses while delivering superior flatness.
Bow Scout® Monitoring System (US patent #9021844) – Improper exit gap settings can introduce up/down bow if the operator is not vigilant to his machine settings. Sensors are added inside the leveler to maintain a consistent exit gap and continuous monitoring was implemented to assure flatness along the length of the strip. The Bow Scout® System was designed to reduce the possibility for leveled sheets to be processed with up and down bow.
FlatTrak® CL Monitoring System (US patent#7185519) – Using tension at the point of plastification proves that minimum backup adjustments are needed to maintain shape flatness. By incorporating a laser system into the line to identify irregularities in the strip, the information is sent through an algorithm to determine where and to what magnitude backup adjustments should be made to remove waves and buckles. A 3D format display provides the operator with real time information to monitor the material for manual adjustments, or the machine can be put into an automatic mode so that continuous changes can be made by the system.
Yield Sensing (patent#9815099) - Monitoring changes in yield within a coil: Leveling needs to yield the material 70 to 80% of the cross section to effectively pull waves and buckles and improve the shape. The leveler operator rarely has yield information on the coils he is running. To insure the correct percentage of plastic was achieved, more sensors were introduced inside the leveler. This new ability allows the machine to properly test the yield strength of the material and correctly set the plunge depth, eliminating guesswork.
This complete Bradbury system is better for the longevity of the equipment, for the material as it equalizes internal stress, and for the operator to use through accurate information. Experience reduced scrap and downtime.
