ABSTRACT:
Vessel mouths (1) are provided with a silane coating in order to improve the pouring behavior. For this purpose, there is an apparatus which has, on a rotatable nozzle holder (14), several spray nozzles (16) and blowing nozzles (17) directed tangentially to the edge (1a) of the vessel mouth (1). A stationary nozzle mandrel (12) forms, by means of its lower centering portion (13), a centering means for the vessel mouth (1). An air flow flows from the centering portion (13) out of air nozzles (20) directed rearwards and prevents spray material from penetrating into the vessel (2). The spray residues and solvent vapors which occur are sucked off from a suction bell (21) surrounding the vessel mouth (1).
