Detector mechanism of the weft applied to a loom characterized in that it acts together with a transparent bore, pierced, perforated or similar, susceptible to being traversed by a light beam when it is devoid or almost devoid of weft, said quill being located inside the the shuttle and because the mechanism itself essentially comprises: a photoelectric cell that becomes active when there is an effective change in the luminous intensity that reaches it, the latter causing a change in the operation of the loom; devices that emit a light beam; a luminous transmitter, which is mounted on the fulcrum and one of whose ends is located in front of the tap while its other extremity moves, due to the action of the fulcrum, in front of the devices that emit the light beam, carried out by its intermediate transmission of the light beam so that, when the bobbin is stripped or almost devoid of a frame, said light beam passes through it and reaches the photoelectric cell, causing in the latter an effective change of its illumination intensity.
