Abstract
Method and device for detecting and compensating defects in rolling mill cylinders, characterized in that the fluctuations of the idle pressure of the fluid contained in the hydraulic jacks arranged between shoulders fast with the working chocks of the machine and the corresponding upright of the latter, are picked up, recorded and then restored during normal operation, with a view to controlling the compensation.
