Abstract

A device and a system for a lacquer transfer with a frame, transfer roller with a circumferential lateral wall, a drive unit, a slit nozzle, the slit nozzle at least indirectly connected to the frame, an outside contact surface of the lateral wall including depressions, the transfer roller mounted rotatably about an axis of rotation at the frame, the drive unit configured to drive the transfer roller for the transfer roller to rotate about the axis of rotation. The slit nozzle includes a supply connection, nozzle-cavity, slit-shaped nozzle-channel and at least one limiter, the supply connection coupled to the nozzle-cavity for supplying lacquer to the nozzle-cavity, the nozzle-channel extending from the nozzle-cavity to a muzzle end formed by the slit nozzle at the end of the nozzle-channel for dispensing lacquer, the slit nozzle configured by the limiter to adjust a cross-section in a restriction area of the nozzle-channel.
