The control unit has a series of indicators which display the control mode to be applied. A data processing unit is associated with the control unit. This processing unit includes a recording system which records the control mode associated with the control units indicators. The system has a central unit which has a counting and memory circuits. These circuits operate in response to control signals derived from the results of the quality control data recorded in the processing unit. The counting and memory circuits furnish an indication of the control mode transmitted towards the processing unit and the control units indicator.
