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.
Claims19
Apparatus for applying a coating to a surface of a workpiece moving in a predetermined direction and comprising:
- conveying means moving the workpiece in said predetermined direction with the workpiece surface exposed for coating;
- coating dispensing means having at least one coating outlet spaced in juxtaposition to said surface for dispensing the coating material to said surface as it traverses the coating outlet, dispensing control means operatively coupled with said dispensing means for initiating and terminating the dispensing of coating thereby as predetermined portions of said moving workpiece surface come into operative alignment with said coating outlet during traverse thereby, and air jet means for substantially preventing tailing of said coating on said surface following termination of dispensing thereof as the workpiece with its coated surface continues movement without substantial tailing of the applied coating, said air jet means including nozzle means juxtapositioned to said coating outlet for directing an air jet in the direction of movement of the surface being coated and upon the coating as it issues from the coating outlet so as to impart at least a component of acceleration to said coating in said predetermined direction.
Apparatus for applying a coating to a surface of a workpiece moving in a predetermined direction and comprising:
- conveying means moving the workpiece in said predetermined direction with the workpiece surface exposed for coating, coating dispensing means having at least one coating outlet spaced in juxtaposition to said surface for dispensing a stream of coating to said surface as it traverses the coating outlet, dispensing control means operatively coupled with said dispensing means for initiating and terminating the dispensing of said stream of coating as predetermined parts of said moving workpiece surface come into operative alignment with said coating outlet and means proximate to the coating outlet for coacting with said stream of coating issuing therefrom by imparting thereto a component of acceleration in the said predetermined directional movement of the workpiece surface under influence of the conveying means for substantially preventing tailing of said stream of coating following termination of dispensing thereof.
Apparatus for applying a glue bead to a surface of a workpiece moving in a predetermined direction and comprising:
- conveying means moving the workpiece in said predetermined direction with the workpiece surface exposed for application of the glue bead thereto, glue dispensing means having at least one glue outlet spaced in juxtaposition to said surface, dispensing control means operatively coupled with said dispensing means for initiating and terminating the dispensing of glue thereby as predetermined portions of said moving workpiece surface come into operative alignment with said glue outlet during traverse thereby, and air jet means for substantially preventing tailing of said glue on said surface and including nozzle means substantially at the egress end of said glue outlet for directing an air jet in the direction of movement of the surface and across the glue stream issuing from the glue outlet for imparting at least a component of acceleration to the issuing glue stream in said predetermined direction.
