To control an insertional speed by measuring the speed in contact-free manner.
The speed of the weft thread in contact-free manner is measured by means of one or more measuring pickups 7.1-7.3 without contact. In the method at least one of the measurement pickups is formed for multiple measurement within the weft insertion and is arranged at or after a first acceleration nozzle 3. Furthermore, measured values are measured in contact-free manner a plurality of times during the weft insertion by means of the at least one measurement pickup (not illustrated) from which values for the speed and/or the path traveled by the weft thread are determined during the weft insertion; and the values determined during the weft insertion are used for the control of the weft insertion.
