An embroidering machine having a plurality of embroidering heads attached to a longitudinally extending carrier and each having a needle drive mechanism for an embroidering needle that is moveable in a vertical plane in the respective embroidering head. Each needle drive is connected to a driven main shaft that is guide through the embroidering machine parallel to the longitudinally extending carriers. For complete mass compensation, each drive arrangement of the embroidering head comprises an externally toothed gear wheel disposed on the driven main shaft and a second externally toothed gear wheel disposed on a compensating shaft oriented parallel to the main shaft. The gear wheels, the external teeth of which mesh with one another, are each provided with a compensating mass in order to completely compensate for the oscillations caused by the longitudinal movement of the needle bar, which is effected in the vertical plane, with the oscillations occurring in the horizontal direction transverse to the main shaft.
