While weaving fabrics ( 501, 502, 601, 602 ) on a weaving machine, in successive weft insertion cycles two weft yarns ( 505, 506, 605, 606 ) are simultaneously inserted at different weft insertion levels between pile warp yarns ( 520, 530, 620, 630 ) which are positioned with respect to the weft insertion levels by a three-position-non-open-shed Jacquard machine. The Jacquard machine is provided to maintain one or several pile warp yarns ( 503, 504, 603, 604 ) in successive operating cycles of the weaving machine in an upper and/or a lower position. The pile warp yarns ( 503, 504, 603, 604 ) in their upper or in their lower position are positioned between the weft insertion levels. Furthermore, a three-position-non-open-shed Jacquard machine and a weaving machine are provided to carry out such a method, and a method to rearrange the harness suspension of a three-position-non-open-shed Jacquard machine.
