Abstract: 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).

Abstract: A weaving loom produces a fabric (F), with warp yarns and in-woven weft yarns. The weaving loom includes a warp delivery unit, heddles to form a shed, a shedding mechanism for moving each heddle vertically along a vertical path, a weft insertion means for inserting each weft yarn in a shed and for releasing each weft yarn at a given location along a weft axis, and a weft delivery means for delivering each weft yarn to the weft insertion means. The weaving loom also includes a programmable clamping means for picking up a first end of each weft yarn and for releasing each weft yarn at any predetermined position along the weft axis, and a programmable mechanism including actuators for semi-closing the shed around the inserted weft yarn at any predetermined position along the weft axis.

Abstract: 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.

Abstract: 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).
