Patent number: 6474919Abstract: A method and apparatus for applying coatings to a portion of the internal bore or threads of a fastener or similar article having an opening on at least one end is provided. A 360° coating with material is provided using centrifugal force to assist in direction the material to a desired surface, which does not require use of a pressurized air stream in order to propell the coating material toward the walls of the article desired to be coated.Type: GrantFiled: February 27, 2001Date of Patent: November 5, 2002Assignee: ND Industries, Inc.Inventors: John S.

Patent number: 6322628Abstract: A powder coating apparatus and method feeds fine powdered coating material such as thermoplastic type material to a succession of discrete articles passing by the apparatus which includes a vibratory feeder bowl and a spiral track for delivering a substantially constant supply of powder coating material to the articles. A sensor is also used to regulate an amount of powdered coating material supplied to an auger to the vibratory feeder. The invention also provides a powder feed system that deposits an excess of powdered coating material than that required to form the coating and provides for recirculation of the powder not ultimately used to form the coating back to the powder feeding apparatus.Type: GrantFiled: September 17, 1999Date of Patent: November 27, 2001Assignee: ND Industries, Inc.Inventor: John S.

Patent number: 6027568Abstract: An apparatus and method for providing a masking, insulating and/or lubricating barrier coating on a portion of the threads and/or other surfaces of discrete objects such as fasteners utilizing a liquid coating material as provided. The present invention can selectively coat threaded and/or unthreaded surfaces of fasteners having odd shapes, deep threads and extended hubs. The fasteners are subsequently elevated and inverted onto a conveying system that moves them away from the area 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.Type: GrantFiled: June 12, 1996Date of Patent: February 22, 2000Assignee: ND Industries, Inc.Inventors: John S. Wallace, Charles M. Stempien, Joseph A. Lopetrone

Patent number: 5964551Abstract: A powder coating apparatus and method feeds fine powdered coating material such as thermoplastic type material to a succession of discrete articles passing by the apparatus which includes a vibratory feeder bowl and a spiral track for delivering a substantially constant supply of powder coating material to the articles, wherein the powdered coating material is mixed with a pressurized airstream that delivers the powdered coating material to the articles. A sensor is also used to regulate an amount of powdered coating material supplied to the auger to the vibratory feeder. The invention also provides a powder feed system that deposits an excess of powdered coating material than that required to form the coating and provides for recirculation of the powder not ultimately used to form the coating back to the powder feeding apparatus.Type: GrantFiled: May 1, 1998Date of Patent: October 12, 1999Assignee: ND Industries, Inc.Inventor: John S.

Patent number: 5928711Abstract: 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.Type: GrantFiled: June 4, 1997Date of Patent: July 27, 1999Assignee: ND Industries, Inc.Inventors: John S. Wallace, Charles M. Stempien, Joseph A. Lopetrone
