| 1. A reed drive of a loom,
with a reed connected to a reed shaft,
with two conversion gears (7, 8) which are located respectively at two outward-facing regions of the reed shaft (3) and which each respectively have a movable input member (11, 12) and a movable output member (13, 14), wherein the output member (13, 14) of each conversion gear (7, 8) is connected fixedly in terms of rotation to a respective associated one of the outward-facing regions of the reed shaft,
with a design of the conversion gears (7, 8) such that the rotational movement of the input member (11, 12) is converted into a reversible rotational movement of the output member (13, 14) of each respective one of the conversion gears, such that the number of complete revolutions of the input member per unit
of time is equal to the number of complete movement cycles of the output member per said unit of time,
and with two electromotive rotary drives (19, 20) respectively having two output shafts (23, 24) that are each respectively connected with a respective one of the input members for rotation in common with and at the same
rotational speed as the respective input member (11, 12).
