ABSTRACT OF THE DISCLOSURE A picking device for the picking motion of a loom uses a pull string for delivering the picking energy to a pivot arm which is capable of being tensioned by way of a cam drive. The pull string can in principle be any elongate structure, e.g. a pull string of steel or a rope of high tenacity aramide fibers. The cam drive includes a toggle lever which is extended by a first cam and urged somewhat beyond its dead center, and which is urged by a second cam back over the dead center to initiate picking. A decelerating string is connected to the pivot arm to decelerate the pivot arm at the end of the pick. -14-
