Disclosed is a weaving machine, including:

    a yarn tensioning system for keeping a pile-warp yarn under tension, including a local control unit, a drive motor Wand a drive roller; anda detection device for detecting abnormal variations in the pile-forming, including: a measuring system, for measuring, with the aid of the drive motor and the drive roller, pile-warp yarn consumption xm of the pile-warp yarn per cycle unit of one or more weft insertion cycles;a reference system, for determining for each cycle unit whether the pile-warp yarn is interlaced in a figure-forming manner and for determining the expected pile-warp yarn consumption xt; anda computing system, for comparing the measured with the expected pile-warp yarn consumption when the pile-warp yarn is interlaced in a figure-forming manner, and for detecting, on the basis of this comparison, abnormal variations.
