Three-position non-open-shed jacquard, comprising a system encompassing two interacting hooks (5), (6) for lifting warp threads (20), (21) on a loom, two first blades (1), (2) which can be moved up and down in opposite phase and which can each transport from their bottom dead centre a hook (5), (6) situated at a selection height (S) - in the event of selection of the said hook -, a control element (16) by which each hook (5), (6) can be selected, a second blade (3) which can be moved up and down in opposite phase with the one first blade (1) and which, from its top dead centre, can transport the hook (5) which interacts with the one first blade (1) - in the event of non-selection of the said hook - from the selection height (S), and means, such as, for example, a fixedly disposed blade (4), for securing at the selection height (S) the hook (6) which interacts with the other first blade (2). Only one control element (16) and one tackle element (12) per system is required, whilst the hooks (5), (6) can be transported by their blades (1), (2), (3) in a jolt-free manner. <IMAGE> |
