Three-position open-shed jacquard machine, comprising a system with two interacting hooks (1), (2) for lifting at least one warp thread on a weaving loom, two first knives (10), (11) which are movable up and down in counterphase, and which in their bottom dead centre can carry along a respective hook (1), (2) from a selection height (S), a first control element (20), by means of which each hook (1), (2) is selectable, so that it can be carried along by its first knife (10), (11), two second knives (12), (13) which are movable up and down in counterphase, and which in their top dead centre can carry along a respective hook (1), (2), from the selection height (S), and a second control element (21), by means of which each hook (1), (2) is selectable, so that it is retained at the selection height (S), while a hook (1), (2) which has not been selected by either of the two control elements (20), (21) is carried along by its second knife (12), (13), and the first (10), (11) and second knife (12), (13) interacting with the same hook (1), (2) are provided in such a way that they move in counterphase. Due to the fact that the control elements (20), (21) are placed one below the other, and only one lifter element (6) is required, said jacquard machine is limited in dimensions, while the hooks (1), (2) can be carried along smoothly from a stationary position by their knives (10), (11); (12), (13). <IMAGE> |
