Abstract

Apparatus for applying a coating to a surface of a moving workpiece comprises a coating dispenser having at least one coating outlet spaced apart from the workpiece surface for dispensing a stream of coating. A dispenser control unit is operatively coupled with the dispensing means for initiating and terminating the dispensing of the stream of coating as predetermined parts of the workpiece surface come into alignment with the coating outlet. The invention provides an anti-tailing device coacting with the stream of coating intermediate the outlet and the workpiece surface for substantially preventing tailing of the stream of coating following termination of dispensing thereof.
