Abstract
An application head for applying, in a non-contacting way, liquid media to a length of material which is movable relative to the application head. The head includes a housing, a cylinder chamber in the housing, in which cylinder chamber a cylinder slide is rotably drivably supported, and a nozzle for ejecting medium, which nozzle can be controlled by the cylinder slide and extends transversely to the direction of movement of the length of material. The cylinder slide includes a cylindrical surface which, from the inside, can seal supply means leading to the nozzle. The cylinder slide also includes at least one surface groove in the cylindrical surface, which surface groove can be supplied with liquid medium and which, as a function of the rotational position, is able to communicate with the supply means leading to the nozzle. The at least one surface groove includes delimiting edges with a variable gradient relative to the circumferential direction.
