The invention relates to a system (1) for labelling individual products (2), in particular packages or goods, comprising a feed device (3) for transporting a respective product (2} along a transport route, comprising a label dispensing device (4) for providing a label (5), and comprising a label application device (6) having a blow head (7) for application of the label (5) to the surface of the product (2), wherein the blow head (7) has a blow head housing (8) having a pressure chamber (9), wherein the blow head housing (8) has, on the side directed towards the feed device (3), a housing part (10) having a plurality of housing openings (11) which connect the interior of the pressure chamber (9) to the environment of the blow head (8) and through which a pulse of compressed air in a venting direction (A) from the housing openings (11) to the feed device (3) can escape, wherein the pressure chamber (9) has a compressed air connection (12) for introducing compressed air into the pressure chamber (9), and wherein the label application device (6) has at least one slide element (13, 14, 15) which is movable between a first position, in which the slide element (13, 14, 15) can completely block at least some of the housing openings (11), and a second position, in which the slide element (13, 14, 15) can at least partially expose a plurality of these housing openings (11). In order to simplify the structure of such a system (1), according to the invention holes (16, 17, 18) are provided in the at least one slide element (13, 14, 15), which holes are arranged in such a way that in the second position of the slide element (13, 14, 15) the holes can be made to at least partially overlap the housing openings (11) which in the first position can be blocked by the slide element (13, 14, 15), and in the first position of the slide element (13, 14, 15) said holes are offset with respect to these housing opening (11), so that no overlap is provided. The invention further relates to a method for labelling individual products (2). |
