System and method for inserting a weft thread

Method for the insertion of a weft thread into a shed of an air jet weaving machine (1), in said method the weft thread (2) being drawn off from a thread store (21), the drawn off weft thread (2) being measured with the help of a measuring apparatus (23.1, 23.2), the weft thread (2) being inserted into the shed by means of a plurality of air nozzles (3, 4, 5.1a-c to 5.na-c) and a control system (10) controlling the compressed air supply of the air nozzles (3, 4, 5.1a-c to 5.na-c) in dependence on measurement values of the measuring apparatus (23.1, 23.2),

• characterized in that
• switch on points (xj) are associated with the air nozzles (3, 4, 5.1a-c to 5.na-c);
• and in that predictor values (xF) for the position of the weft thread tip are formed with the help of the measurement values;
• and in that, in particular, a safety value or factor is contained in the predictor values (xF) for the position of the weft thread tip;
• and in that the control system (10) charges one or more of the air nozzles with compressed air as soon as a predictor value (xF) for the position of the weft thread tip, which is formed with the help of the measurement values, reaches the switch on point (xj) of the relevant air nozzle or air nozzles respectively.
