METHOD AND APPARATUS FOR PROCESSING FASTENERS

摘要

An apparatus and method for providing a masking, insulating and/or lubricating barrier coating on a portion of the threads (80) and/or other surfaces of discrete objects such as fasteners (26) utilizing a liquid coating material as provided. The present invention can selectively coat threaded (80) and/or unthreaded surfaces of fasteners (26) having odd shapes, deep threads, and extended hubs (86). The fasteners (26) are subsequently elevated and inverted onto a conveying system (14) that moves them away from the area (45) where the coating material is applied directly into a heat treatment device such as an oven in a continuous on-line process that does not require manual handling of the fasteners (26).
