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 device for cutting through pile threads on a weaving machine, including a cutting means (6), connected to a transmission body (5), and a rotatable drive means (1), which rotates alternately in the one and the other rotational direction and meshes with the transmission body (5) so that its rotation motions are converted into a back-and-forth displacement of the cutting means (6), wherein, via the transmission body (5), a pushing force is exerted on the cutting means (6). The transmission body (5) can be non-endless and interact with one rotatable drive means (1). Also, a weaving machine provided with such a cutting device.

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).
