<p>A device for presenting the weft in weaving looms comprises a plurality of oscillating presenting rods having their free end in the form of an eyelet for the weft thread and being controlled by a corresponding plurality of levers. A magnet device causes the oscillation of the levers under the control of a weft selection device, and a transversal bar operates the levers, being apt to engage an appropriate seat of those of the levers having been selected by the selection device through the magnet device. The transversal bar has a flattened section with mixed-line contour, apt to freely insert itself into the correspondingly shaped seat of the control levers of the device, and to respectively cooperate with the seat, depending on the reciprocal position between the transversal bar and the seats of the levers. Moreover, the transversal bar is fixed to an end of at least one guide lever which controls the position thereof during its movements and which is pivoted, at its other end, to a connecting rod oscillating about a fixed point.</p> |
