Abstract
A heddle frame actuator device is provided for a negative or positive heddle frame drive. The actuator device employs at least one flexure spring for imposing a spring force vertically on and in the plane of the heddle frame. In some embodiments, a pair of flexure springs, for example of U-shape, Y-shape and endless loop shape may be used. The ends of the springs connected to the loom frame may also be adjusted so that the prestressing of the springs can be varied.
