Patent ID: 6866209

Claim:
An application head ( 11 ) for applying liquid media to a length of material ( 22 ) which is movable relative to the application head, the application head comprising a housing ( 12 ) having a cylinder chamber ( 20 ), a cylinder slide ( 13 ) rotatably driveably supported in the cylinder chamber ( 20 ), and a nozzle ( 18 ) for discharging the liquid medium, the nozzle being controllable by the cylinder slide ( 13 ) and extending transversely to the direction of movement of the length of material, wherein the cylinder slide ( 13 ) comprises: an inner chamber ( 29 ) adapted to be supplied with liquid medium; a cylindrical surface ( 35 ); a first surface groove ( 27 ) in the cylindrical surface, which can be supplied with liquid medium and which, as a function of the rotational position of the cylinder slide, can communicate with the nozzle ( 18 ); first radial bores ( 28 ) extending from the inner chamber ( 29 ) to the first surface groove ( 27 ); and a second surface groove ( 31 ) in the cylindrical surface, which accommodates a sealing strip ( 33 ) which is biased toward the surface of the cylinder chamber ( 20 ), wherein the second surface groove ( 31 ) is associated with the first surface groove ( 27 ) in such a way that, upon rotation of the cylinder slide the second surface groove ( 13 ), follows the first surface groove ( 27 ).
