Abstract: A shed forming device for a shuttle loom includes a carrier (6) for at least one shuttle (5, 5') and a stationary frame (1) accommodating a reed of wires or dents (7) disposed in a plane extending parallel to the direction of movement of the shuttle carrier (6). A freely rotatable toothed wheel (4) is mounted on the shuttle carrier (6) in front of the corresponding shuttle, at an angle to the reed plane and in engagement with the reed wires or dents (7) to form a shuttle shed. The toothed wheel (4) is mounted on the opposite side of the reed plane with respect to the shuttle carrier to better accommodate the shuttle carrier.
