ABSTRACT:
A device for picking up, turning over, folding and aligning a sleeve cloth that is continuously carried by a moving conveyer. The device comprises a jaw located above the upper surface of the moving conveyer and a lifting blade located below the bottom surface of a moving conveyer. The leading edge of the sleeve cloth is detected by a sensor that triggers the lifting blade to push a front portion of the cloth up and into the jaw which holds the cloth as the conveyer continues to move. The cloth is folded and aligned by the action of the conveyor belt and a first blower, which blows air on a top side of the cloth, and a second blower, which blows air on a bottom side of the cloth.
