Abstract
The picking mechanism is provided with two torsion bars. One torsion bar is stressed in order to accelerate a gripper projectile of the loom. The second torsion bar, upon release of the first torsion bar, is temporarily connected to the first torsion bar so that energy can be stored by the second torsion bar via a double-arm lever. During a return motion of the acceleration lever to a picking position, the second torsion bar is relieved of tension by delivering the stored energy to the drive shaft of the picking mechanism via the double arm lever. The picking mechanism thus uses only little energy.
