1. A stacker module for a folder-gluer machine, the stacker module being located downstream of a transfer module in a direction of transportation of the folder-gluer machine and configured to receive folding boxes from the transfer module, wherein the stacker module comprises:
a loading surface configured to receive a plurality of folding boxes and to descend vertically as a number of folding boxes on the loading surface increases,
a linearly movable ejector configured to be moved from a retracted position to an extended position and eject a stack of folding boxes from the loading surface, and
an upper guide configured to move between a clearing position which is vertically distant from an upper surface of the stack, and a guiding position, in which the upper guide is located closer to the upper surface of the stack,
wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the extended position,
wherein the upper guide comprises a first elongated guide member and a second elongated guide member,
wherein the first elongated guide member and the second elongated guide member extend in the direction of transportation, and
wherein a lateral distance between the first elongated guide member and the second elongated guide member can be modified.
