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.
