Vacuum drum for a labeling unit, labeling unit having such a vacuum drum, and method for producing a vacuum drum

A method comprising producing a vacuum drum a vacuum drum for a labelling unit of a labelling machine that labels containers with a label having a first end and a second end, said vacuum drum being rotatable about a drum axis and comprising a plurality of segments, said segments being arranged next to each other along a circumferential direction of said vacuum drum so as to collectively form a circumferential surface of said vacuum drum, wherein said segments comprise a first segment that comprises a first vacuum-holder that holds said first end, a second vacuum-holder that holds said second end and that is offset from said first vacuum-holder along said circumferential surface of said vacuum drum, a carrier plate, and a label arc between said first and second vacuum holders, wherein said first vacuum-holder comprises a first housing and said second vacuum holder comprises a second housing, wherein producing said vacuum drum comprises carrying out an additive manufacturing process to manufacture at least one structure selected from the group consisting of said carrier plate, said first housing, and said label arc, wherein said first segment comprises a vacuum line that supports said first housing on said carrier plate, and wherein producing said vacuum drum further comprises manufacturing said vacuum line using an additive manufacturing process.
