ABSTRACT:
An automatic sewing machine comprises a stand, on which a workpiece guide and feed device is mounted. This device substantially comprises an x carriage, a y carriage displaceable thereon and a lever with a workpiece holder for the displacement of workpieces on a workpiece receiving plate. The y carriage is drivable by a drive stationary on the stand by way of a shaft which is likewise stationary on the stand and passes though the x carriage. A drive for the y carriage is supported on the shaft by means of a torque/linear bearing. Driving the shaft takes place in proximity to the sewing head and at a distance from an auxiliary station so that inaccuracies of guidance occasioned by torsion of the shaft are minimized during the sewing operation.
