A reed drive of a loom comprises a reed shaft ( 3 ) connected to the reed ( 1 ). A conversion gearing ( 7, 8 ) each having a respective input element ( 11, 12 ) and a respective output element ( 13, 14 ) is located at the ends of the reed shaft ( 3 ). The input elements ( 11, 12 ) are coupled to the driven shafts ( 23, 24 ) of electromotive rotary drives ( 19, 20 ) for effecting a common rotational motion of the same rotational speed. The conversion gearings ( 7, 8 ), alone, serve to convert the rotating motion of their input elements into a motion of the output elements ( 13, 14 ) whose direction of rotation can be reversed. To this end, the output elements ( 13, 14 ) are coupled to the reed shaft ( 3 ) in a rotationally fixed manner. As a result, a motion cycle of an input element ( 11, 12 ) corresponds to the motion of the reed ( 1 ) from one reed stop to the next reed stop so that the number of complete rotations of an input element ( 11, 12 ) is equal to the number of complete motion cycles that the reed shaft ( 3 ) executes in the same unit of time.
