A stacker for stacking labels (6) die-cut from a continuous web by a die cutter (3) into vertical stacks (35). The stacker is of the kind that comprises at least one stacking chute (10) having an upper opening (24) and a number of mainly vertically arranged walls (36, 37, 38, 39), at least one overlying belt conveyor (11) having a conveyor belt (12) designed with a number of suction holes distributed along the belt and having a lower run (13) with a direction of conveyance running from the die cutter (3) to the stacking chute (10), and a suction box (19) located above the lower run (13) and connected to a vacuum source communicating with the suction holes of the lower run (13) via the suction box in an area around the die cutter 83) but not in an area around the stacking chute (10). A channel (44) for receiving the lower run (13) of the conveyor belt (12) or a lower part of this run is designed in at least a front wall (38) of the walls of the stacking chute (10), seen in the direction of conveyance, said channel is extending this direction. The stacker has a simple structure and is able to stack products at the same rate as a rotary die cutter can die-cut the products. Thereby, it is possible to utilise the capacity of the rotary die cutter completely.
