The invention pertains to a device for gathering sheets ( 3 ) with feeder stations ( 15 ) that are arranged in a row and consist of a magazine ( 20 ) for respectively accommodating a stack ( 4 ) of identical sheets, a separating device ( 50 ) that tilts an exposed edge region ( 3 b) of the respective bottom sheet away from the stack ( 4 ) and a transport device ( 30 ) that withdraws the sheet from the stack parallel to the longitudinal direction of the edge region, and with a collecting conveyor ( 10 ) that features pushers ( 13 ) for the gathered stacks ( 2 ). In order to achieve a high processing speed, the invention proposes that the separating device ( 50 ) features at least one suction element ( 51 ) for tilting away at least one corner of the sheet ( 3 ), and that the transport device for withdrawing the sheet ( 3 ) is formed by a traction means conveyor ( 30 ) with individually actuated grippers ( 32 ) that are anchored on revolving traction means ( 31 ) within certain distances from one another and at least two of which take hold of the exposed edge region ( 3 b), wherein the traction means conveyor ( 30 ) is inclined toward the collecting conveyor ( 10 ) in order to deposit the withdrawn sheet ( 3 ) on the stack ( 2 ) being formed directly in front of the pusher ( 13 ) of the collecting conveyor ( 10 ). The invention makes it possible to reliably decollate head-folded signatures if the suction element ( 51 ) is arranged on the upstream corner of the stack ( 4 ).
