This weaving machine (2) is for simultaneously weaving top and bottom pile fabrics (F2, F4) presenting some pile patterns (P2, P2′, P4) and including tufts, made from warp yarns (24), binding warp yarns (14, 16) and inwoven weft yarns. This machine includes a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) and a weft insertion unit (8) for inserting the weft yarns in the shed. The machine also includes a beating-up mechanism (32), a take up system (70), a drawing-in unit (26), and a control unit (80). A treatment unit (90) is located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (20) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).

A method for simultaneously weaving, on a face-to-face weaving machine, two pile fabrics each including an area with and without pile. For a pick corresponding to the area without pile, a dead pile thread is placed between the backing fabric and a patterning weft and a dead pile thread is placed opposite the backing fabric with respect to the same patterning weft. An additional fabric is formed in the area without pile by the first and second dead pile threads woven with the patterning wefts, this additional fabric covering the backing fabric.

A method for face-to-face weaving of two at least partially pile-free fabrics (I), (II) in which weft threads (101-104),(201-204) are inserted between warp threads (1a-14a,1b-14b) of warp thread systems with figure warp threads (1a-8a),(1b-8b) that are allocated to respective fabrics (I,II) and are either pattern-determining in that fabric or are incorporated therein, whereby at least one set (1a,1b), . . . (8a,8b) of two identical figure warp threads is provided per pair of neighbouring warp thread systems, while the two figure warp threads of each set belong to a different warp thread system (1a-14a), (1b-14b) and are allocated to a different fabric (I,II), so that each set of figure warp threads per pair of neighbouring warp thread systems provides a figure warp thread in both fabrics (I,II) to determine the pattern.

This weaving machine (2) is for simultaneously weaving a top pile fabric (F2) and a bottom pile fabric (F4), each pile fabric presenting some pile patterns (P2, P2, P4) and including tufts, made from warp yarns (24), binding warp yarns (14, 16) and inwoven weft yarns. This machine comprises a pile warp yarns feeding unit (20), a binding warp yarns feeding unit (18), a shedding unit (6) for creating a shed with the pile warp yarns and the binding warp yarns (14, 16). A weft insertion unit (8) is used for inserting the weft yarns in the shed in successive insertion cycles. A beating-up mechanism (32) is used for beating the weft yarns into the shed. A take up system (70) is used for taking-up the two pile fabrics. A drawing-in unit (26) draws the pile warp yarns from the pile warp yarn unit (20) and a control unit (80) controls operation of the weaving machine (2). This weaving machine also comprises a treatment unit (90) located, along a path of the pile warp yarns (24), between the pile warp yarns feeding unit (26) and the shedding unit (6), for applying different segments of treatment on at least some of the pile warp yarns (24).

A jacquard machine includes a plurality of yarn moving elements and in association with each yarn moving element a yarn moving mechanism having an output cord connected to the yarn moving element, a plurality of setting bars extending substantially in a first direction corresponding to a weft direction and positioned adjacent to each other substantially in a second direction longitudinal end regions and a cooperation region arranged between the longitudinal end regions for the cooperation with a plurality of yarn moving mechanisms, a plurality of position adjustment bars extending substantially in the second direction, wherein in each one of the two longitudinal end regions of the setting bars two position adjustment bars are provided adjacent to each other, and a plurality of connecting members for connecting the setting bars to the position adjustment bars, wherein in each longitudinal end region of each setting bar one connecting members is provided such as to be connectable to either one of the two position adjustment bars arranged in a respective one of the longitudinal end regions of the setting bars.
