Abstract
A monitoring system for a fluid weft insertion loom monitors the significant operative events of each weaving cycle of the loom, e.g. yarn supply withdrawal, insertion nozzle actuation and yarn end arrival, and indicates the occurrence of each such event, preferably in terms of the elapsed time of such occurrence from a fixed reference point of the loom cycle, for example front dead center. The indications of the relative timing of the occurrences of such events is preferably retained on corresponding visual displays until the successful completion of each weaving cycle or in the event of a defective cycle until the defect is corrected and the loom is restarted. Preferred individual sensing units for the respective significant operative events are also disclosed.
