Upgrading Corrugator Roll Stands
|
 |
PROBLEM
After 25 years of operation, the hydraulic drum brakes on the roll stands had become a high maintenance item. Additionally, it had become increasingly difficult to maintain consistent tension control.
|
|
SOLUTION
A careful review of the application was necessary to determine the required thermal capacity and detail the envelope restrictions.
It was determined that a new air actuated brake with an integral cover could be mounted with minimal changes. The upgrade also included adding an automatic danger control system which has resulted in a significant quality improvement.
In conclusion, the brake upgrade reduced maintenance cost, improved quality and increased safety. These rolls stands are ready for another 25 years.
