ABSTRACT:
A sheet turning machine includes two slidable platforms, one of which is ascending while the other is descending, the upward travel of one of the platforms being synchronized with the downward travel of the other platform. The ascending platform is arranged between two vertical guide columns solidly fastened to a fixed chassis, while the descending platform is guided between two columns solidly fastened to a frame which tilts about the fixed chassis. The ascending platform is arranged under the field of action of a suction pump. A turning bridge is arranged above the descending platform and includes an endless conveyor belt which has a lower or return run part which diverges in a direction perpendicular to the columns guiding the descending platform. At the front of a roller whereat the endless belt returns, there is an air generator capable of maintaining a sheet of paper fixed to the belt while the sheet, travelling with the belt, passes from the upper run to the lower or return run.
