Abstract
An improvement in apparatus for applying a coating to a surface of a moving workpiece including a coating dispenser having at least one coating outlet for dispensing a stream of coating. A dispenser control unit is operatively coupled with the dispenser for normally initiating and terminating the dispensing of the stream of coating as predetermined parts of the workpiece surface come into alignment with the coating outlet in response to the speed and position of the workpiece surface. The invention provides a minimum coating control coacting with the dispenser control unit for depositing a coating of a selectable minimum length to at least one portion of the workpiece surface, said selectable minimum length being substantially less than that achievable by said dispenser control unit alone.
