摘要： The present invention relates to a stacker module (28) for a folder-gluer machine (1). The stacker module comprises a loading surface (90) configured to receive a plurality of folding boxes and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector (76) configured to be moved from a retracted position (RP) to an extended position (DP). The stacker further comprises an upper guide (110), configured to move between a clearing position (CP) which is vertically distant from the upper surface of the stack, and a guiding position (GP), in which the upper guide is located closer to the upper surface of the stack, and wherein the upper guide is in the guiding position when the ejector is moved from the retracted position to the evacuation position.
