Abstract
A shed forming device () for a power loom has a plurality of heddle shafts, to which a drive mechanism with a plurality of servo motor groups () is assigned. The servo motor groups are located below each of the heddle shafts (through), in each case as a cluster, and they are located with their pivot axes (through) on a circle, an ellipse, or a similar figure. They are also axially offset from one another. Each servo motor (through) is provided with a driven lever (through). The free ends of all the levers are located approximately at the center of the circle or ellipse or other figure of revolution. They are connected to the heddle shafts (through) via connecting rods (through) and form various angles with the connecting rods (through). The result is a drive mechanism with little inertia, low resilience, and little play. Very fast shaft motions can be attained in a controlled way.
