  • Patent number: 4144825
    Abstract: A device for the removal of flexible workpieces which are draped over a workpiece holding arm and which hang downwardly from each side thereof, in particular, over a work-handling arm of an arm-down sewing machine, comprises a horizontally disposed carrying arm or rod which is adapted to receive the sewn material and support it so that portions hang downwardly from each side thereof. A material engagement clip, which has a pair of clamping arms arranged below the carrying arm, is mounted for movement in directions substantially parallel to the carrying arm in order to move the clamping arms on respective sides of the workpiece and subsequently to move the clamping arms together so that they clamp the workpiece and strip the workpiece from the carrying arm when the clamping arms are moved outwardly from the carrying arm.
