Abstract
A blow device for weft threads in weaving machines, in particular a blow device which makes use of a nozzle of the type which consists of a housing, a thread guide duct extending through the housing and a first or main blower situated in the housing and working with the thread guide duct to transport a weft thread to the shed of the weaving machine. The nozzle has a second or threading blower also situated in the housing that cooperates with the thread guide duct for threading the nozzle. The second blower has at least one blow duct which intersects the thread guide duct at an angle so as to thrust a weft thread presented at the entry of the thread guide duct through the thread guide duct when supplied with air. A central system deactivates the main blower when the threading blower is activated.
