摘要： A ROLLING MILL WITH TWO ROLLS HAS AN IMPROVED CONTROL ASSEMBLY WHICH COMPRISES ELECTROMAGNETIC OR PHOTOELECTRIC SENSORS WHICH METER THE GAP BETWEEN THE ROLLS WHILE REMAINING OUT OF CONTACT WITH THEM. THE OUTPUT OF THIS SENSING ARRANGEMENT IS COMPARED WITH A REFERENCE VALUE TO YIELD AN ERROR SIGNAL WHICH IS FED TO AN ADJUSTMENT MECHANISM TO CHANGE THE ROLLER GAP IF NECESSARY. FURTHER SENSORS FOR METERING A BENDING IN THE ROLLS CAN BE PROVIDED AND COUPLED WITH A DEVICE FOR STRAIGHTENING THE ROLL. IN ADDITION A GUAGE MEASURING THE THICKNESS OF THE ROLLED WORKPIECE CAN BE USED TO PROVIDE A CROSS CHECK ON THE FUNCTIONING OF THE APPARATUS.
