This publication discloses a method and an apparatus for attaching a label (17') to an outer surface of a package (11). In accordance with the method, the label (17') is printed by a printer (3) onto a label web (17), the label (17') is separated from the web (17), and tacked to the wrap of the package (11). The label (17') printed according to the invention is introduced onto a suction plate (1), which is arranged to an end of a pivoted swing arm (8), with a printed side of the label facing the suction plate (1) so that an rim of the label web (17) extends over a pressure roller (2). Vacuum is applied to the suction plate (1) in order to hold the label, the label (17') is separated from the label web (17) by a shear means (4), an adhesive precoat is applied on an unprinted side of the label (17'), the package (11) is moved, and the pivoted swing arm (8) is rotated against the package (11) by an actuator (5) so that one edge of the label (17') is brought into an adhering contact with the outer surface of the package (11) by the line pressure exerted by the pressure roller (2), whereby the label (17') is attached by its tacky surface to the surface of the package (11) in a nip formed between the pressure roller (2) and the package (11) while the movement of the package (11) rotates the pressure roller (2). The method in accordance with the invention reduces appreciably the chance of missing the label (17') and provides an easy implementation of automated operation. (Figure 1) |
