FIELD: looms. SUBSTANCE: control device of high-speed rotary dobby for loom has key with lateral recess whose width equals thickness of control ring with which it interacts and the length of stroke of key in its installation inside or withdrawal from radial recess in big end of crank or in drive shaft. Control ring is of elliptical shape and installed and held in the state of rest by means of V-shaped spring. It is forced to swing from side to side relative to spring symmetry axis under the action of pusher bar which is actuated by cam mechanism and moved by needle quadrant controlled by programmer to act on one of two hollows made in swinging quadrant.
