A labeling device for applying labels onto a material web, which is moved in a transport direction at a web speed, comprises a label dispenser and a transferring device, which takes over the labels from the label dispenser by means of holding means, moves the labels towards the material web and applies the labels onto the material web at a transfer location. The holding means of the transferring device can be moved in the transport direction and opposite the transport direction in a circulating path at a variable circulating speed, said holding means moving in the transport direction at the web speed when the holding means are located at the transfer location.
A labeling device (1) for applying labels (2) onto a material web (10), which is moved in a transport direction (T1) at a web speed (V1), comprising a label dispenser (4) and a transferring device (7), which takes over the labels (2) from the label dispenser (4) by means of holding means (8), moves the labels (2) towards the material web (10) and applies the labels (2) onto the material web (10) at a transfer location (11), characterized in that the holding means (8) of the transferring device (7) can be moved in a circulating path at a variable circulating speed (Vx) in the transport direction (T1) and opposite the transport direction, said holding means (8) moving in the transport direction (T1) at the web speed (V1) when the holding means are located at the transfer location (11).
A labeling device according to any of the preceding claims, characterized in that the transferring device (7) is a rotating cylinder having a rotational axis transversal to the transport direction (T1) and that the holding means (8) are arranged on the shell surface of the cylinder.
A labeling device according to any of the preceding claims, characterized in that the movement of the holding means (8) on the circulating path thereof may be reversed.
A labeling device according to any of the preceding claims, characterized in that the holding means (8) are formed as vacuum suction devices, preferably having adjustable vacuum force.
A labeling device according to any of the preceding claims, characterized by an adhesive applicator (12) for applying adhesive onto the side of the labels (2), which faces away from the transferring device (7).
A labeling device according to any of the preceding claims, characterized in that the labels (2) are longitudinal labels and that the label dispenser (4) dispenses the labels with the longitudinal axis thereof transversal to the transport direction (T1).
A labeling device according to any of the preceding claims, characterized in that there is arranged, at the transfer location, a counter-pressure device (9) opposite to the transferring device (7), in particular a rotating counter-pressure roll having a rotational axis transversal to the transport direction (T1).
A labeling device according to any of the preceding claims, characterized in that the label dispenser comprises a cutting device (13), which cuts individual labels (2) off from a web-like label material.
