Method for weaving pile fabrics and pile fabric woven with such a method

Method for simultaneously weaving, on a face-to-face weaving machine, two pile fabrics each including at least one area with pile and at least one area without pile, wherein:

• a top backing fabric and a bottom backing fabric are woven one above the other, each with:
• at least one tension warp thread,
• at least one binding warp thread,
• inner wefts, which are inserted between the binding warp thread and the tension warp thread on a pile side of the tension warp thread,
• back wefts, which are inserted between the binding warp thread and the tension warp thread on a back side of the tension warp thread, opposite to the pile of the fabric,
• patterning wefts, are inserted on a pile side of the tension warp threads, outside of the backing fabric,
• at least one patterning pile threads is interlaced in the upper backing fabric and in the lower backing fabric, in order to form pile legs in the area with pile,
• wherein, for at least one pick, corresponding to the area without pile, at least a first dead pile thread is placed between the backing fabric and a patterning weft and a second dead pile thread is placed opposite the backing fabric with respect to the same patterning weft, wherein an additional fabric is formed in the area without pile by the first and second dead pile threads woven with the patterning wefts and wherein this additional fabric covers the backing fabric.
