ABSTRACT:
The present invention relates to dobbies incorporating double swinging levers for weaving looms. In order to simplify the construction of the reading device in the case of synchronized dobbies capable of operating both in reverse motion and in forward motion, there is associated with each selection hook a releasable retaining member which immobilizes it in one or the other of two stable positions of operation, so that the reading device need exert only a fleeting action (pulse) on one or the other of two heels of the hook, whereby no sustained action of the reading device is necessary.
