Shed-forming devices for weaving mechanisms which create three positions of the warp threads in a Jacquard loom. The shed-forming devices include moveable spindle catches capable of being vertically displaced by knives driven in oppositely reciprocally oscillating motion. Each shed-forming device includes four moveable spindle catches which are adapted to be displaced in pairs by the knives. A first spindle catch of each pair is adapted to be supported by a second spindle catch of each pair. Each shed-forming device also includes five pulleys which are vertically aligned and are connected to the catches by funicular elements such that the five pulleys may be separated from each other in a variable manner depending upon the position of the four spindle catches.
