Abstract

A method for the insertion of a weft thread (2) into a shed of an air jet weaving machine (1) is presented in which the weft thread drawn from the thread store (21) is accelerated by means of an acceleration nozzle (3, 4) and supplied to the shed; the weft thread is transported further in the shed by means of a plurality of auxiliary nozzles (5.1 a-c to 5.n a-c); and measured values dependent on the speed of the weft thread and/or on the path traveled by the weft thread are measured in contact-free manner by means of one or more measurement pickups (7.1, 7.2, 17). 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 (6, 6.1-6.5) 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.
