Abstract: A labelling unit and a method for labelling containers is provided. Said method provides rapid and reliable switching movements with low noise development and low wear of the mechanical components in that suction bars for suctioning label areas at places where container gaps occur can be actively switched back to an inner position, in which they do not come into contact with a gluing unit, and in that the switching process is triggered with the aid of a stationary toggle lever.

Abstract: A device for applying glue onto labels, includes a drum rotatable about a predetermined rotational axis and, a glue application unit for applying glue onto an external surface of the rotatable drum. The glue application unit includes a receiving space for receiving the glue as well as a supply unit for applying the glue to the receiving space which is arranged relative to the drum such that any glue present in the glue application unit contacts the drum in a predetermined contact area. The glue application unit includes a first wall element, which contacts the drum during operation, and a second wall element arranged behind the first wall element in the direction of movement of the drum and which also contacts the drum. At least one wall element is elastically pressed against the external surface of the drum.

Abstract: A device (1) for applying glue onto labels, comprising a drum (2) rotatable about a predetermined rotational axis (X), including a glue application unit (4) for applying glue onto an external surface (2a) of the rotatable drum (2), said glue application unit (4) including a receiving space (16) for receiving the glue as well as a supply unit (18) in order to supply the glue to the receiving space (16), and which is arranged relative to the drum (2) in such a way that any glue present in the glue application unit (4) contacts the drum (2) in a predetermined contact area (B), said glue application unit (2) including a first wall element (12), which contacts the drum (2) during operation, as well as a second wall element (14) which is arranged behind the first wall element (12) in the direction of movement of the drum (2) and which also contacts the drum (2). According to the invention at least one wall element (12, 14) is elastically pressed against the external surface (2a) of the drum.
