Abstract: An electrostatic paint atomizer connected to a discharge station at high voltage is supplied, via an isolating conveying line, with individual divided-off quantities of paint enclosed between two pigs from a loading station at the other end of the conveying line. The paint is conveyed by a transport device supplying a thrust medium (compressed air or insulating liquid) to discharge the paint in the discharge station. A reverse transport device operating with compressed air transports the pigs back to the loading station. The length (L) of the conveying line between the loading and the discharge stations and the length (l) of a divided-off quantity of paint, are dimensioned to provide a sufficiently long isolating path (L-l) to avoid a voltage flashover. A continuous supply of paint is achieved with two parallel conveying lines, through which quantities of paint are metered with an offset from each other.

Abstract: In equipment for powder-coating, workpieces such as escalator steps are subjected to a current treatment in an anodizing unit. A conveying means advancing carriers for the workpieces is lowered over a tank so that the workpieces in transit are immersed in and continue transit within a bath and after a specific dwell time are lifted back out of the bath at the end of the tank. Arranged in the tank region is a current feed, such as a bus bar, which extends parallel to the travel path of the conveying means. Each carrier is provided with a current take-off which connects the carrier with the current feed. The current connection is produced on lowering the carrier into the bath and interrupted on raising the carrier from the bath.

Abstract: A chemically washed workpiece is heated and degreased by a heating and degreasing section in a process for delivering the workpiece in a base which is then cooled down in a cooling section. The workpiece is then delivered onto the base by a lift-up unit and is coated by the adhesion of the powder coat and the curing operation during the passage of pipes of an electrostic coater, a curing section and the like. Furthermore, the workpiece is again delivered into the base by a lift-down unit and discharged after being cooled down during the passage of pipes of the cooling section i.e., the units of each step being arranged separately into a lower mechanism group and an upper mechanism group, and the cooling section also serving to cool the workpiece after the heating, degreasing and curing. Accordingly, the overall length of the apparatus is shortened.

Abstract: A device for applying a double-sided coating to a substrate comprises three transport lines which are mutually connected by conveying stations in the form of belt-type conveyors. The substrate is placed onto a paper web, and the upper surface of the substrate is coated with the liquid to be applied in a spraying station in an electrostatic field; subsequently dried; turned through 180.degree. in the horizontal direction by a first belt-type conveyor; and passed onto a punched conveyor belt which is endlessly guided about a suction roller. The substrate is turned upside down by the suction roller, through a jet of compresed air. The substrate is transported onto a second belt-type conveyor where it is horizontally turned through 180.degree. and conveyed onto the third transport line, in which it is again passed through a cleaning station and a spraying station where the other surface of the substrate is coated with a liquid resist.

Abstract: A baking oven is divided into a first baking oven and a second baking oven. A conveyor line is also divided into two sections, a first conveyor line section being so disposed as to pass through the first baking oven only, and a second conveyor line section being so disposed as to pass through the second baking oven only. A substrate is coated with a paint and then conveyed through the first baking oven while being so supported by a carrier with a rotating device and being rotated about its approximately horizontal axis extending in a longitudinal direction thereof with the rotating device. The rotation of the substrate is carried out at a speed which is high enough to prevent the paint coated from sagging due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force.

Abstract: Cup lubricating process and apparatus in which cup-shaped can bodies are controllably conveyed in spaced relationship to each other through a lubrication application chamber. Lubricant is atomized to particle sizes permitting them to be gas borne and introduced into such chamber from a plurality of locations about the travel path for can bodies. Apertures in the bottom wall of such chamber direct lubricant particles directly into the open ends of such can bodies for flow impingement deposition on internal surfaces thereof. Provision is made for augmenting surface deposition by electrically charging at least a portion of the gas-borne lubricant particles in such chamber and electrically grounding can bodies individually during passage through such chamber. Endless loop conveyor means are provided with adjustable features enabling a travel path to be adapted to differing dimension can bodies.

Abstract: An electrostatic powder spray coating method and apparatus for producing evenly coated continuous films of thermoplastic and thermosetting powders on substrates or parts having electrically conductive geometric complex surfaces enables the use, without the occurrence of "cobwebbing," of significantly higher charging voltages for the spray gun in the spray coating of preheated substrates and parts, thus allowing faster coating lines. The invention features the use of a grounded electrically conductive ring for grounding the ionized field in the powder discharge region of the spray gun.

Abstract: A method for electrostatically applying a thermoplastic resin coating on a threaded portion of a fastener to provide a self locking element thereon. A plurality of fasteners are moved by a spaced pair of endless belts passed a spray station where a stream of powdered resin is directed toward the threaded ends of the fasteners. The fasteners and resin are polarized to opposite polarities at the spray station whereby the powdered resin is attracted to and clings to the threaded ends of the fastener and extends completely about the circumference of said ends. Air jet nozzles located downstream of the spray station may direct streams of compressed air against certain portions of the powdered resin to remove the resin therefrom to provide uncoated lead threads and to regulate the distance that the resin extends circumferentially about the threaded ends to provide a coating extending between 180 degrees and 360 degrees about the threaded ends.
