Abstract: A driving apparatus for an oscillating catcher of a sewing machine includes a toothed pinion being eccentrically mounted on a driving shaft for the catcher for the sewing machine. A transmission device, having teeth, is guided in a back-and-forth movement by an oscillating crank drive, with the teeth of the transmission device engaging the tooth pinion on the driving shaft. By arranging the toothed driving gear eccentrically on the driving shaft of the catcher, it is possible to substantially increase the speed of the point of the catcher when it seizes the loop of the upper thread offered by the needle.

Abstract: A sewing machine having an adjustable head module, which has a machine body and a machine housing, along with a support plate for supporting a workpiece, and a support arm. Driving device for driving a looper in a looper system in the support plate, and for a needle bar in the adjustable head module at the end of the support arm is provided. The head module is pivotably mounted on the support arm, and pivotable, or swinging, about a horizontal pivot bearing in a first sewing direction and axially displaceable in a second sewing direction, in which the first and second sewing directions are perpendicular to one another. The head module can be adjusted on the body of the sewing machine in the sewing direction and transversely to the latter in a simple manner and locked into the exactly adjusted, and optimal, position.
