Method for simultaneously weaving two pile fabrics (C1, C2) with shadow cut pile zones on a face-to-face weaving machine, wherein: - an upper backing fabric and a lower backing fabric are woven one above the other with: - at least one filling warp yarns (f1, f2), - at least one binding warp yarn (b1, b1', b2, b2'), - weft yarns (Wi, Wb) inserted in successive weft insertion cycles (P1-P32) between binding warp yarns and filling warp yarns, the weft yarns comprising inner weft yarns (Wi), which are inserted on a pile side of the filling warp yarns, and back weft yarns (Wb), which are inserted on a back side of the filling warp yarns, opposite to the piles (D1, D2) of the fabric, - patterning pile yarns are interlaced in the upper backing fabric and in the lower backing fabric, each patterning pile yarn externally turning around an inner and a back weft yarns (Wi, Wb) in each backing fabric, characterized in that at least one patterning pile yarn follows a path where: - in a first series of weft insertion cycles (P1-P16; P1-P16; P1-P14; P1-P16; P1-P16; P1-P12; P1-P12) and at least in a first backing fabric (F1, F2), the patterning pile yarn follows at least twice a path where it turns externally around an inner weft yarn (Wi), then externally around a consecutive back weft yarn (Wb), and - in a second series that are consecutive in a warp direction of weft insertion cycles (P20-P32; P20-P32; P15-P32; P17-P32; P20-P32; P20-P32; P24-P32) and at least in the first backing fabric (F1, F2) the patterning pile yarn follows at least twice a path where it turns externally around a back weft yarn (Wb), then externally around a consecutive inner weft yarn (Wi). - an upper backing fabric and a lower backing fabric are woven one above the other with: - at least one filling warp yarns (f1, f2), - at least one binding warp yarn (b1, b1', b2, b2'), - weft yarns (Wi, Wb) inserted in successive weft insertion cycles (P1-P32) between binding warp yarns and filling warp yarns, the weft yarns comprising inner weft yarns (Wi), which are inserted on a pile side of the filling warp yarns, and back weft yarns (Wb), which are inserted on a back side of the filling warp yarns, opposite to the piles (D1, D2) of the fabric, - at least one filling warp yarns (f1, f2), - at least one binding warp yarn (b1, b1', b2, b2'), - weft yarns (Wi, Wb) inserted in successive weft insertion cycles (P1-P32) between binding warp yarns and filling warp yarns, the weft yarns comprising inner weft yarns (Wi), which are inserted on a pile side of the filling warp yarns, and back weft yarns (Wb), which are inserted on a back side of the filling warp yarns, opposite to the piles (D1, D2) of the fabric, - patterning pile yarns are interlaced in the upper backing fabric and in the lower backing fabric, each patterning pile yarn externally turning around an inner and a back weft yarns (Wi, Wb) in each backing fabric, - in a first series of weft insertion cycles (P1-P16; P1-P16; P1-P14; P1-P16; P1-P16; P1-P12; P1-P12) and at least in a first backing fabric (F1, F2), the patterning pile yarn follows at least twice a path where it turns externally around an inner weft yarn (Wi), then externally around a consecutive back weft yarn (Wb), and - in a second series that are consecutive in a warp direction of weft insertion cycles (P20-P32; P20-P32; P15-P32; P17-P32; P20-P32; P20-P32; P24-P32) and at least in the first backing fabric (F1, F2) the patterning pile yarn follows at least twice a path where it turns externally around a back weft yarn (Wb), then externally around a consecutive inner weft yarn (Wi).
