A device for handling a sheet pile in a printing press includes a pile chamber with at least one opening of a size at least through which the pile is passable horizontally, a lifting platform in the pile chamber for receiving the sheet pile thereon, a lift drive for vertically adjusting the platform, and a screen assigned to the opening and adjustable between a first operating condition wherein the screen covers the opening, and a second operating condition wherein the opening is free from being covered by the screen. A conveyor section horizontally shifts the pile through the opening when the lifting platform is at a transfer level. The conveyor section includes a first conveyor subsection within the pile chamber and at least a second conveyor subsection outside and adjoining the pile chamber. The first and second subsections have alternating states of occupancy during operation. They are alternately occupied by a pile and not occupied by a pile. A conveyor section drive shifts the pile along the conveyor section. The screen is operationally independently changeable from the first to the second operating state for predetermined states of occupancy of the conveyor subsection and when the lifting platform is at the transfer level and, the screen is operationally independently changeable from the second to the first operating state thereof after the pile has been shifted completely from one of the conveyor subsections to the other.
