Abstract
A face-to-face weaving machine with a weft insertion device (,), (,) is provided in order according to a top and a bottom insertion path to insert weft threads between warp threads (,). A lifting device (,) works together with shed-forming devices (,), (,), (,), (,), of which first shed-forming device (,) is provided in order to bring warp threads (,), (,) above and between the insertion paths; second shed-forming device (,) is provided in order to bring warp threads (,), (,) between and below the insertion paths; third shed-forming device (,), (,) is provided in order to bring warp threads (,) above, between and below the insertion paths, such that the ratio (H/h) between, on the one hand the intermediate distance (H,), (H,) between two warp thread positions and on the other hand the lifting height (h) applied by the lifting device, is greater, preferably 1.5 times greater, for the third shed-forming device (,), (,) than for the first (,) and the second shed-forming device (,). A method is also provided for face-to-face weaving a pile fabric to be utilized on such a weaving machine. Because of this all shed-forming devices (,), (,) can work together with the same lifting device (,), (,), so that an ideal shed formation is possible by utilizing one single jacquard machine. Such a weaving machine is less expensive and less complex than the existing machines.
