ABSTRACT:
A device including a ball carrier table having an opening in it scenter provided with a turntray with driven carrier balls is used to change the orientation of an article, such as a stack of sheets of boards. The carrier balls are driven by an arrangement including one or more continuous belts having an upper surface engaging a lower part of each of the carrier balls. The motion of the turntray is obtained by an arrangement for rotating the turntray around an axis extending peripendicular to a plane of the table and the turntray can be shifted vertically between a lower position in the plane of the table to an upper position raised above the plane of the table.
