Abstract (en)

[origin: WO8102852A1] According to the method, a mechanical control signal is generated according to the product supply for the control of a metering valve (9). To obtain powerful control operation with a high precision and reliability and of a simple and compact construction, the mechanical control signal is first transformed into a pneumatic signal which is transmitted as an input signal to a servocontrol (41) for regulating the product supply and/or to a servocontrol (18) for the start up or shut down of the milling cylinder. A device specially adapted to this method is a cylinder mill which comprises a mechanical signal transmitter (13, 15) operating a pneumatic regulating valve (17) of which the output is connected to the input of a servocontrol (18) actuating the metering valve (9) and/or the start up and shut down of milling cylinders (1, l", 2, 2").
