Abstract
A system for inserting a weft thread into a shed of an air jet weaving machine includes a thread store with a measuring apparatus, a plurality of air nozzles for the insertion of the weft thread and a control system which is connected to the measuring apparatus in order to be able to control the compressed air supply of the air nozzles in dependence on measurement values of the measuring apparatus. Switch-on points are associated with the air nozzles, with the control system charging one or more of the air nozzles with compressed air as soon as a predictor value for the position of the weft thread tip, which is formed with the help of the measurement values, reaches the switch-on point of the relevant air nozzle or air nozzles respectively.
