Abstract
A shedding device in a jacquard loom, having a heddle with a retracting spring rigidly anchored in the loom or to the floor for urging the heddle to a lower shed forming position. To suppress the development of resonance in the spring, a core element is provided, which contacts the inside of the spring at points spaced apart from one another and forces the spring to take a course which deviates from the rectilinear. As a result, friction forces that contribute to damping the spring motion are created between the spring and the core element.
