ABSTRACT:
By a first conveying device printing products are fed in an imbricated formation (S), in which each printing product rests on the following one, the fold edge of the folded products forming the trailing edge. The printing products are pushed into an intermediate stack from below. The respectively uppermost product of this intermediate stack is seized in the region of the fold edge by at least one sucker of a sucker arrangement, raised upward and brought into the conveying region (F) of a second conveying device. The latter has individually controllable grippers which are arranged at regular intervals, circulate along a closed path, seize the fold edges delivered by the sucker arrangement and convey away the printing products thus seized. By forming an intermediate stack, from which the printing products are then raised by the sucker arrangement at the desired rate and fed to the grippers, even imbricated formations (S) occurring with irregularities can be processed satisfactorily.
