(54)	Method and device for controlling the weft stock in weft suppliers for mechanical-pick looms, including means for notifying the color selection

(57) A method is described for controlling the weft stock in weft supplying devices (P) to mechanical-picking looms (TE'), by restoring the loops unwound from the drum, including means (Can Bus) for real-time transmission of the color selection. The method substantially consists in generating virtual signals (USP'-USP"-etc.) replacing loop-passage signals (USP), starting at the weft picking instant (t1) which follows the instant (t0) of reception of the color selection data transmitted by the transmission means; each of the virtual signals (USP'-etc.) indicating the passage of one loop being unwound from the drum of the supplier (P).
