Abstract
A three-position open-shed jacquard machine has a system with two interacting hooks (1), (2) for lifting a warp thread on a weaving loom. First and second knives (10), (11) are movable up and down in counterphase and in their bottom dead-center position can carry along a respective hook (1), (2) from a selection height (S). A first control element (20) selects each hook (1), (2) so that it can be carried along by the first and second knives (10), (11). Third and fourth knives (12), (13) are movable up and down in counterphase and in their top dead center position carry along a respective hook (1), (2), from the selection height (S). A second control element (21) selects each hook (1), (2) so that it is retained at the selection height (S). A hook (1), (2) which has not been selected by either of the two control elements (20), (21) is carried along by the third and fourth second knives (12), (13). The first and second knives (10), and third and fourth knives (11), (12), (13) interacting with the same hook (1), (2) move in counterphase. The control elements (20), (21) are positioned one below the other, and only one lifter element (6) is required. The hooks (1), (2) can be carried along smoothly from a stationary position by the respective knives (10), (11); (12), (13).
