摘要

In a process for controlling a weft thread feed and measurement device for an air jet loom, a release signal is generated for a weft thread insertion, whereupon a stop element is moved into a release position and releases the weft thread at an actual release time. The actual release time is recorded at the moment of insertion and compared with a reference release time which depends on the textile machine. A parameter for the release signal which influences the actual release time is then adjusted in function of the difference detected between the actual release time and the reference release time in such a manner that on the next insertion the actual release time is approximately equal to the reference release time. A suitable device for carrying out the process has a passage sensor or a detection device (I) for determining the actual release time and a comparison and equalization circuit for comparing and adjusting a parameter for the release signal which influences the actual release time.
