Zusammenfassung: | In an apparatus for preparing a surface layer on an object moving in longitudinal direction, which is realized with a receptacle (3) for receiving a coating material, wherein on two opposite side walls (15) of the receptacle (3) an upper acoustic oscillation generator (6, 6 min ) is arranged for forwarding in a stream the coating material to the object (3), further with the receptacle (3) a closing member (F) following in an elastic manner the pressure changes occuring in the inner space of the receptacle (3) is coupled, the receptacle (3) communicates with an inlet of a hopper (18) arranged in the upper part of a coating vessel (4) having wall members (24) guiding in transverse direction an object (1), wherein in the coating vessel (4) from one side a trough (17) communicating with the outlet or of the hopper (18) and from the other side underneath the trough (17) a lower acoustic oscillation generator (6'') are arranged, further between the coating vessel (4) and the receptacle (3) a transporting unit (S) having an inlet opening (22) arranged oppositely to the lower acoustic oscillation generator (6'') and an outlet opening (23) arranged over the upper acoustic oscillation generators (6, 6 min ) is provided. |
