FIELD: package industry. ^ SUBSTANCE: invention concerns labeling devices and can be applied in various industry spheres for roll item labeling, particularly in labeling of cartridges of shelled industrial explosives with paper shell. Labeling device includes transverse bar, guide lines, rollers mounted on slides and moving along guide lines. Roller contact is mediated by spring. Transverse bar with rollers is mounted on bracket rotating around its axle. Colourant feed is performed by dropper consisting of case, bush sleeve, plunger and sprung valve. Colourant is fed to bush sleeve cavity from tank through 'a' orifice, and colourant discharge is performed through 'b' orifice and nozzle. ^ EFFECT: labeling quality independent from environment temperature and device c leaning frequency, sparing consumption of labeling material, reduced effect of human factor in operation process. ^ 5 dwg |
