In order to coat strip a catenary portion of the strip is suspended through a powder coating subsystem which includes a powder coating booth and a curing oven. The coated strip is the recoiled onto a rewind reel. In the alternative, the strip may be stopped and sheared at an input region and presheared blanks introduced to the powder coating subsystem. The blanks are placed on a belt conveyor, which transports them into the powder coating booth. The blanks are then passed in a conveyor through the powder coating booth and over for subsequent restacking. After passing out of the oven, and before coiled or stacking occurs, the strip or blanks pass through a quench and an air dryer. The powder coating subsystem can be incorporated into a larger pre-treating, cleaning, embossing or post-processing line.Type: GrantFiled: October 27, 1993Date of Patent: August 8, 1995Assignee: Hunter Engineering Company, Inc.Inventors: Subbiah Sankaran, Axel W.

Patent number: 5382450Abstract: An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is transferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor.Type: GrantFiled: November 23, 1993Date of Patent: January 17, 1995Assignee: Blodgett & Blodgett, P.C.Inventor: Richard Salisbury

Patent number: 5356497Abstract: A method for forming a sheet material permeable to gas and not permeable to water includes forming the sheet material by hot pressing two materials together, and discharging static electricity to the sheet material in order to form a number of apertures in the sheet material. The apertures have a size smaller than that of water particles and larger than that of gas particles such that the sheet material is permeable to gas and not permeable to water.Type: GrantFiled: May 5, 1993Date of Patent: October 18, 1994Inventor: Chi S.

Patent number: 5281446Abstract: Single ply paperboard containers are wax-coated by directing a relatively narrow spray band of atomized wax towards the interior surfaces of the containers being treated. The spray band is volumetrically asymmetrical and is oriented relative to the interior surfaces of the container such that its volumetric asymmetry is directed towards the bottom circumferential seam between the tubular side wall and bottom wall of the containers. In this manner, a minimal (but fluid-impervious effective) nonsaturating amount of wax will be applied to the interior surfaces of the container so as to preserve the vivid appearance of color graphics and/or indicia that may be printed on the exterior surface of the container. At the same time, the volumetric asymmetry and orientation of the spray band ensures that a maximum amount of wax will be applied at or near the circumferential bottom seam so that a fluid-impervious fillet seal may be established thereat.Type: GrantFiled: August 7, 1991Date of Patent: January 25, 1994Assignee: Sweetheart Cup Company Inc.Inventors: Derek S. Matheson, Wesley R. Bush, Carlton L. Kemmet, Donald C. Lundgren, David W. Norwood, Robert Brown, Romano Balordi, Onisim Kransnokutsky

Patent number: 5262207Abstract: Plastic automotive panels are painted electrostatically by coating the rear of the panel with conductive material to serve as the grounded terminus of an electrostatic paint deposition field and paint is sprayed onto the front of the panel by conventional electrostatic spray guns. The coating is applied to the panels by spraying a conductive salt or a conductive primer to the rear surface and allowed to dry, or the panel is formed with the conductive coating molded in situ. In the latter case, conductive material is sprayed onto a mold surface or a metal foil or metallized plastic sheet is inserted into the mode before the part is formed to result in a panel with a conductive rear surface. Also, in-mold coating can be used to apply a conductive coating during the formation of a plastic panel.Type: GrantFiled: September 3, 1991Date of Patent: November 16, 1993Assignee: General Motors CorporationInventors: David P. Garner, Alaa A. Elmoursi
