Abstract
Anilox rollers of doctor units are provided with cells, arranged over the sleeve surface along spiral lines, in order to guarantee that the wear of the doctor blades, employed at said anilox rollers, is as uniform as possible. To prevent the ink from issuing between end-sided seals and the anilox rollers, one end section is provided with narrow sections that exhibit no cells or one end section is provided with end-sided sections, on which the cells are arranged on spiral lines with shallower pitch, or one end section is provided with end sections, on which the cells are arranged on spiral lines with opposite pitch.
