Abstract: A powered paper turner is an automated load turning device specifically designed to turn a paper stack sandwiched between a pair of pallets in a work and turn printing process. The paper turner is mounted on wheels, with a rotating module rotating about an axle mounted on a moving support beam to give the module its rotational capability. A slide that secures the paper stack moves horizontally within the rotating module to shift the center of gravity. As the support beam moves up and down a pair of guide rods on linear bearings, the rotating module rotates about the axle. During a downstroke of the moving support beam, the paper stack rotates from a vertical position to a horizontal position. The stack is then shifted, so that during an upstroke of the moving support beam, the paper stack completes a 180° rotation.

Abstract: A load turning device specifically designed to turn paper in a work and turn printing process includes a pair of slides mounted on a pair of parallel tracks. To turn the paper stack, the paper turner is positioned so that a first slide is under the pallet on which the paper stack rests. The second slide is lowered to rest on top of the paper stack, and the slides are locked in position relative to each other. The paper turner is then turned, using wheels to support the weight, until the stack is in a horizontal position. The slides and the paper stack are then moved to the opposite end of the tracks. The paper turner is again rotated until it is in a vertical orientation, rotated 180° from its original position. The printed sides of the paper are now facing downward, and the paper is ready to be loaded into the printing press.
