An apparatus for stacking sheets has a frame defining a stacking station and a pair of substantially parallel and transversely spaced guides on the frame in the station each having a horizontal lower edge and a planar inner face turned toward the other guide. Each guide is formed with a downwardly open notch opening at the respective lower edge and housing a respective guide plate vertically displaceable between a lower position projecting below the respective lower edge and an upper position wholly above the respective lower edge. Each guide plate has an inner face substantially coplanar with the inner face of the respective guide. A vertically displaceable platform is provided in the station underneath the guides along with a support rack horizontally displaceable in the station between an extended position directly above the platform and upwardly engaging the guide plates and a retracted position not directly above the platform and out of engagement with the guide plates. A conveyor delivers a succession of sheets one after the other at a predetermined level and in a predetermined direction parallel to the guides to the station so that the sheets drop down between the guides and are deposited on the rack in the extended position thereof and on the platform in the retracted position of the rack.
