Abstract
The weft yarn tensioning device is employed in a weft changing operation for a weaving machine. The tensioning device has a rod which oscillates at the cadence of the weaving machine transversely of the weft yarn group. The rod deflects the yarns to retaining elements which hold the deflected yarns during upward movement of the rod. A control device is provided for the retaining elements whereby the weft yarn which is to be picked can be released during the upward movement of the rod. The retaining elements can be electromagnetically operated or mechanically operated.
