  • the container transport device can also be designed as a linear machine.
  • the ones in the Figure 2a The extent of the areas 201 and 202 shown along the transport direction of the labels is to be understood as an example. In a preferred embodiment, the extent of the areas 201 and 202 along the transport direction is selected such that at least part of the label 102 is applied to the container 108 before the label 102 has passed through the area of the guide body 202 that can be subjected to a vacuum and is in the area 201 which is not exposed to any negative pressure. In this way, the label can be prevented from falling off the vacuum conveyor belt 106.
  • the label 102 In order to achieve a precise application of the label 102 to the container 108 and in particular to avoid slipping of the label 102, it can be provided that at least a quarter, a third or half of the length of the label 102a is applied to the container 108 , before the label 102 and in particular its rear end viewed in the transport direction has passed through the area of the guide body 202 that can be subjected to a negative pressure.
  • the guide body 110 of the vacuum transport device 111 comprises an area 204 which can be subjected to a negative pressure and an area 205 assigned to the transfer device 107 and which can be subjected to an excess pressure.
  • the guide body can be manufactured using a generative process.
  • excess pressure to the area 205, the detachment of the label can be supported and the transfer to the container 108 compared to that in the Figure 2b discussed embodiment can be further improved.
  • an overpressure in the area 205 assigned to the transfer device 107 detachment of the label 102 can also be ensured, for example, if the label sticks to the vacuum conveyor belt due to electrostatic forces.
  • the area 204 and the area 205 can be designed as two cavities separated from one another by a wall 207.
  • the area 204 that can be subjected to a negative pressure can, for example, be connected to a vacuum pump and can be subjected to a negative pressure in the range from 0.9 bar to 0.95 bar or from 0.8 bar to 0.95 bar or from 0.5 bar to 0.95 bar.
  • the area of the which can be subjected to negative pressure Guide body 110 can include openings on a side 204a of the area 204, which is intended for label transport.
  • the vacuum conveyor belt can be perforated so that the labels 102 conveyed by the vacuum conveyor belt 106 can be detached from the vacuum conveyor belt 106 by the excess pressure applied to the area 205 of the guide body 110.
  • the area 205 can be connected to a pressure supply, for example.
  • the area 205 can also include openings on one side 205a and the vacuum conveyor belt 106 can be perforated so that the labels can be detached from the vacuum conveyor belt 106 by means of the excess pressure applied to the area 205.
  • the area 205 is subjected to an overpressure in a range from 1 bar to 1.05 bar or from 1 bar to 1.1 bar or from 1 bar to 1.2 bar.
  • the specified pressure ranges are to be understood as a pressure which prevails in the area of the guide body subjected to excess pressure and not as a pressure difference with respect to an ambient pressure.
  • the strength of the overprint can be selected based on a property of the label, such as a weight of the label, its area and/or its rigidity. For example, with comparatively heavy labels, a higher overpressure can be used, while with comparatively light labels, a lower overpressure can be used to release the label from the vacuum conveyor belt.
