An applicator roll (1) is described for a labeling apparatus for paying out and applying self-adhesive labels, which with each operating cycle moves one self-adhesive label into a dispensing position underneath an applicator roll. Depending on the printing mechanism used in the labeling apparatus, whether printing an even or an odd number of digits, it is advantageous to arranged a profiled ring (32) formed on a sleeve (31) of the applicator roll (1) in the center or off center. In addition, label formats of different widths require applicator rolls of different widths. These problems are solved in the applicator roll (1) described here in that its sleeve (31) supports two cylindrical jackets (34) on either side of the profiled ring (32). The cylindrical jackets (34) are axially displaceable on the sleeve (31) and can be releasably, positively locked in several positions against axial shifting, preferably by mutual engagement of an annular collar (38) and an annular groove (40). In this way, the applicator roll (1) can be adapted to printing mechanisms with even or odd numbers of digits and to labels of different widths. |
