  • Fully hydraulic edger for plate mills
    Patent number: 9016100
    Abstract: A fully hydraulic edging system suitable for use in wide plate mills is disclosed. The need for electro-mechanical screws to effect large movements of the side rollers is avoided by employing a pull-back hydraulic cylinder for this purpose. The main hydraulic cylinders are switched to a non-operational mode during large movements thus avoiding the need for large volumes of hydraulic fluid to be transferred under high pressure.
    Type: Grant
    Filed: February 9, 2010
    Date of Patent: April 28, 2015
    Assignee: Siemens PLC
