ABSTRACT:
A nozzle actuating and adjustment system for applying sealant to a can lid member comprising a nozzle which has a sealant dispensing opening, a needle valve means, a needle valve seat surface and a sealant flow passage for enabling flow of sealant material onto the lid member. The needle valve is selectively axially movable between an open sealant applying position and a closed non-flow position relative to the needle valve seat surface. A spring means is operatively associated with the needle valve means to normally hold the needle valve means in the closed lowered position. A needle valve actuator solenoid is operatively connected to the needle valve for selectively causing axial upward movement of the needle valve from the closed position to the open position by a predetermined axial distance to provide a predetermined sealant flow gap in the nozzle means to dispense a predetermined amount of sealant material during a predetermined dispensing time period. A flow gap adjustment solenoid is operatively connected to the needle valve actuator solenoid for selectively changing the amount of axial movement of the needle valve caused by the actuator solenoid so as to selectively vary the sealant flow gap and the amount of sealant material dispensed during a predetermined dispensing time.
