ABSTRACT:
An apparatus for feeding a workpiece in a machine tool, particularly in a sewing machine, comprises a main conveyor for longitudinally conveying the workpiece in a feeding direction and an auxiliary conveyor for transversely conveying the workpiece to align the same, which auxiliary conveyor comprises a conveying mechanism, which precedes or succeeds the main conveyor and is engageable with the workpiece as it is guided along a guideway and comprises conveying elements which are adapted to be driven to move transversely to the feeding direction. To ensure exact, simple and functionally reliable feeding, the conveying mechanism of the auxiliary conveyor is incorporated in a generally cylindrical rotor, which is rotatable about an axis of rotation, which is normal to the feeding direction and parallel to the direction of the guideway and is adapted to be driven at a surface speed which is related to the speed of travel of the main conveyor, the conveying elements of the auxiliary conveyor consists of a plurality of conveyor belts, which are regularly distributed about the axis of rotation of the rotor and are adapted to be driven by an adjusting drive independently of the rotation of the rotor.
