The present invention relates to a separator device (22) for a folder-gluer machine, the separator device being configured to divide a shingled stream of folding boxes into separate batches, the separator device comprising a vertically movable separator head and at least one upper evacuation conveyor belt.

A lower conveyor system (30) has a lower evacuation conveyor belt, such that the folding boxes are pinched between and transported by the upper evacuation conveyor belt and the lower second conveyor belt in unison.
