Abstract
A pneumatic thread holder for a selvedge device on weaving machines includes a blower nozzle, a support for the weft thread located underneath the nozzle, and an opening for the weft thread in line with the blower nozzle. The opening is enlarged transverse to the blowing direction of the blower nozzle in order to prevent air current reflections or deviations from occurring when the tucking needle passes beneath the opening, thus ensuring that the end of the weft thread remains held in a correct position by the pneumatic holder.
