A control device for operation of a system for treating a surface of a solid running substrate by dielectric-barrier electrical discharge in a controlled gaseous atmosphere, comprising (A) a system which includes (i) a treatment device through which a substrate to be treated runs at a speed, (ii) the system is connected to the treatment device for supplying the treatment device with gas, (iii) the system is connected to the device for supplying the treatment device with electrical power in order to produce the electrical discharge and (iv) the system for sucking out the gas (B) a data processing unit designed to receive, as input, a datum regarding the speed at which the substrate is running through the treatment device, the data processing unit being connected, on the output side, to the gas supply system, to the electrical power supply system and to the gas suction system, in order: (a) upon starting the treatment device and when the running speed of the substrate is greater than a predetermined speed, to carry out the following actions: initiate operation of the suction system, initiate operation of the gas supply system, initiate operation of the electrical power supply system, and (b) upon stopping the device and/or when the running speed of the substrate drops to a level below a predetermined speed to carry out the following actions: interrupt operation of the electrical power supply system, interrupt operation of the gas supply system, and interrupt operation of the suction system.
A control device for operation of a system for treating a surface of a solid running substrate by dielectric-barrier electrical discharge in controlled gaseous atmosphere, comprising
A process for controlling operation of a system for treating a surface of a solid running substrate by dielectric-barrier electrical discharge in a controlled gaseous atmosphere, wherein the system includes a treatment device through which a substrate to be treated runs at a speed, means connected to said treatment device for supplying the treatment device with gas, means for supplying the treatment device with electrical power in order to produce the electrical discharge and means for sucking out the gas, comprising the steps of measuring the speed at which the substrate runs through the device and carrying out the following actions:
