Abstract
The pacing motion which is adapted to be stepped on in respect of individual wefts has a sliding wedge with a return spring. The wedge is displaceable on an output shaft into a groove of an input shaft in both directions of rotation. The motion also includes a locking lever actuatable off-load by a control signal. The lever locks and unlocks a release lever which is driven by a drive element and actuates the wedge. A transmission with a delay feature or a resilient damping insert can be used as an impact-reducing element to absorb some of the impact of the wedge in the groove. Freely actuatable electromagnets can be used both as actuating elements and as the drive element.
