Abstract
Apparatus for singularizing stacked paper sheets has a rotary withdrawing conveyor with an annulus of equidistant satellites having suction cups which attract successive lowermost sheets of a stack in a magazine adjacent a first portion of an endless path for the satellites. The satellites deliver the sheets into a second portion of the endless path where the leaders of the sheets are caused to project radially outwardly and to enter the spaces between the open jaws of grippers which are transported by an endless chain in such a way that a gripper which is about to receive a sheet is moved at the speed of the oncoming sheet-carrying satellite and in the same direction. The satellites have discs cooperating with an endless band serving to gradually release a sheet which is in the process of advancing with a gripper.
