ABSTRACT:
Printing products (13) are fed by a conveyor track (11, 14) to a stack compartment (17), which can be charged from above, in an imbricated formation of the kind in which the printing products (13) lie in pairs congruently one on top of the other. In order to be able to form stacks containing an odd number of printing products, a retaining device (24) is provided, adjoining the exit of the conveyor track (11, 14), which retaining device upon activation temporarily lifts the upper printing product (13) off the one lying underneath.
