In order to avoid a pushing-together or pulling apart of an imbricated stack of sheets during reversal around the reversing roller (3) of a rotary sheet feeder (1), belt-like flexible guide means (18) are used which are disposed at intervals over the axial length of the reversing drum (3), one end of the feeder frame side forming an intake gusset while the other end of each is articulated through a spring (19) on a rod (20) which connects the side walls of the feeder frame (7). The flexible guide means (18) pass between the reversing element (13) and the intake side roller (8) of the second belt conveyor (6) which forms the withdrawal table, the reversing element (13) like the other rollers of the second belt conveyor being mounted on a pivotable frame (11) which is articulated in turn on the feeder frame (7) and is initially tensioned in the direction of the reversing drum (3).
