Abstract
An apparatus for providing a barrier coating on a portion of discrete objects such as fasteners utilizing a liquid coating material is provided. The present invention introduces either a plurality of loose or interconnected parts onto a magnetized conveyor system and optically senses when parts are present. When parts are sensed, the sensor triggers a discrete shot of liquid coating material such as a fluorocarbon to be deposited onto a predetermined portion of each part. These parts can then be transferred to a second magnetized conveyor system that supports an opposite surface of the parts than the first conveyor. The invention can also remove excess coating material and also be provided with dryers or heaters to fix the coating material to the parts if necessary.
