<p>The device is a weft-carrier projector comprising one or more solenoids and a hole for projecting the weft carrier. The latter is held so that it can move in the projection hold and control devices apply a discharge current to the solenoid or solenoids. Specifically, the control devices comprise a control circuit which applies a carrier circuit voltage to thyristors connected in series with the solenoid. This discharges one or two condensers coupled with the solenoid to an electrical source.</p> |
