Abstract:
1. A method of applying labels to objects using a vacuum drum having an outer peripheral surface and a plurality of apertures in the outer peripheral surface, and using first and second structure for controlling vacuum pressure to the plurality of apertures, the method comprising: supplying vacuum pressure to at least some of the plurality of apertures; adjusting the vacuum drum to vary at least one of an axial configuration or a circumferential configuration of the plurality of apertures to which vacuum pressure is applied, by adjusting one of the first structure that controls vacuum pressure to the plurality of apertures, or the second structure that controls vacuum pressure to the plurality of apertures, wherein the first structure operates in a different manner than the second structure, such that labels of different sizes can be supported on the outer peripheral surface by the applied vacuum pressure; and supporting a label on the outer peripheral surface with the applied vacuum pressure.
