A shuttle embroidery machine having an embroidery frame which is displaceable in accordance with a predetermined program with respect to the machine frame both in vertical and in horizontal directions at its two ends by separate respective drives each, each drive having a motor whose rotation can be transmitted via a transmission as a vertical or a horizontal displacement, respectively, to the embroidery frame and cross guides permitting independent movement of the embroidery frame in the horizontal or vertical directions. In order to increase the precision of positioning of the embroidery frame and at the same time to make its drives simpler and less expensive, at least one additional drive, controlled jointly with the end drives, is arranged between the ends of the embroidery frame for the vertical displacement of the embroidery frame.
In a shuttle embroidery machine having an embroidery frame which in accordance with a predetermined program is displaceable at its two ends with respect to a machine frame both in vertical and in horizontal directions by separate drives, respectively, one of the drives at each of the ends being for the horizontal displacement and another of the drives being for the vertical displacement, each said drive having a motor, the rotation of which via a transmission is transmittable, as a vertical or horizontal displacement, respectively, to the embroidery frame, and cross guides permitting independent movement of the embroidery frame in the horizontal and vertical directions, respectively, the improvement comprising
