摘要：
A device for driving at least one needle bar on embroidery or sewing machines from a main drive shaft by means of a crank drive. In order to create a simple construction of high efficiency, low noise and little wear, the axis of rotating of the crank mechanism is arranged parallel to the main drive shaft. The bearing for defining the axis of rotation of the crank mechanism is adjustable in height such that the magnitude of the stroke of the needle is unchanged.
