Abstract (en)
The method consists in using, in order to detect the passage of at least one moving magnet (M) associated with the flywheel (VO) that rotates jointly with the weft winding arm, a first magnetic sensor and a second magnetic sensor (H1-H2) which are mutually spaced by a preset distance (D) and are adjacent to the circular path of the at least one magnet, and in sampling the signals (WSP1-WSP2) of the first and second sensors (H1-H2) in order to extract from them, as regards counting the number (NS) of turns wound on the drum (TA), transition criteria (DX -> OUT; OUT -> DX; and, vice versa, A ≥ N) which indicate that a complete rotation of said arm (BR) has occurred and that said number (NS) of turns has consequently increased or decreased. <IMAGE>
