Abstract
The arrangement is operative to pick at least one weft yarn for weaving machines and comprises a pair of weft yarn tensioning devices the second of which provides a loop of yarn whose length is equal to the length of weft yarn transferred by the main nozzle to the projectile and which is released for transfer to the projectile before the first tensioning device releases the weft yarn for picking. The second tensioning device draws back an equally long portion of the weft yarn after picking. The arrangement prevents a weft yarn end from not being transferred from the nozzle to the projectile so that the weft yarn is not picked.
