Abstract
The present invention relates to a method for face-to-face weaving of a pile fabric on a weaving machine, pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) being interlaced alternately around a weft yarn (1) in the upper fabric and around a weft yarn (1) in the lower fabric and non pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) being interlaced in one of the backing fabrics in accordance with a predetermined pattern, the said weaving machine comprising at least three weft insertion means and that at each weft insertion cycle only one weft yarn is inserted, the non pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) to be interlaced are positioned on a different level (N1, N2) and, in successive series of four weft insertion cycles (a, b, c, d) each time during two successive weft insertion cycles one weft yarn (1) being inserted (a, b) under the two levels (N1, N2) and one weft yarn (1) being inserted above the two levels (N1, N2) and each time, during two other successive weft insertion cycles (c, d) one weft yarn (1) being inserted in each of these weft insertion cycles between the said levels (N1, N2).
