1. A labelling device for labelling individual packages, the labelling device comprising:
a feed assembly for transporting the individual packages;
a label dispensing assembly for dispensing a label that is removable from a strip of material in a dispensing direction to a transfer position; and
a label application assembly for applying a label dispensed into the transfer position to a surface of one of the individual packages;
wherein the label application assembly includes a label suction assembly configured to pick up a label dispensed by the label dispensing assembly and fix the label in the transfer position,
wherein the label suction assembly is configured to generate a first air stream and to guide said first air stream in such a manner that both a suction force and a pressing force are exerted on the label in the transfer position,
wherein the label suction assembly comprises a first negative pressure generating unit for generating the first air stream, and wherein the label suction assembly comprises a first air guiding unit associated with the first negative pressure generating unit for guiding the first air stream to exert the pressing force on a label pressure side and/or a adhesive side thereof,
wherein the label suction assembly has one or more first suction openings associated with the first air guiding unit and through which the first air stream that is generated is guided into the label suction assembly, and
wherein the first air guiding unit has an incoming air channel which begins with the one or more first suction openings and which extends as far as the first negative pressure generating unit, wherein the first air guiding unit has an outgoing air channel which begins at the first negative pressure generating unit and which extends as far as at least one first outlet opening of the label suction assembly through which the first air stream is guided for exerting the pressing force on the label, and wherein the incoming air channel and the outgoing air channel are fluidically connected together by way of the first negative pressure generating unit.
