Abstract (en)

[origin: DE19602513C1] A process is for monitoring the functioning of electrically controlled magnetic valves for controlling the air vol. through nozzles for the insertion of a pick into a weaving shed of an air jet loom. The course of the control current has a characteristic feature over a period of time in the case of each magnetic valve. The feature is monitored e.g. through peak value detection and a signal is produced and/or the weaving process is interrupted in the absence of the feature or in the event of a delay in the feature.
