Abstract
A weaving machine starts-up in slow speed operation during a first weaving cycle following the machine start. To help avoid weft breaks, a method is provided to hold a weft thread inserted into the loom shed during the first weaving cycle. A sensor monitors the weft insertion. The inserted weft thread is held by binding threads at a location downstream from an inlet side of the loom shed, before the weft thread is bound by the warp threads. The binding of the weft thread by the binding threads is carried out dependent on a signal of the sensor.
