    Abstract: A method and apparatus are disclosed for the spraycoating of the interior of a hollow body, one region of which, e.g. a seam, must receive a heavier coating than the remainder of the surface to be sprayed. A single spray coating operation is performed, in which a relatively heavy spray jet is concentrated on the seam and a relatively thin cloud of coating material is used to coat the entire interior surface of the body. Preferably, a cloud of electrostatically charged coating material is formed by an atomizer fed by a feed conduit from which a certain amount of coating material is diverted to be formed into the relatively highly concentrated spray jet directed at the seam. The relatively high-velocity particles of material of the spray jet which is concentrated onto the seam and the relatively low-velocity particles of material of the coating cloud together produce on the seam a thinner layer of material than would normally suffice and which, nonetheless, adheres well.

    Abstract: A novel metallic squeeze-out tube suitable for packing paste-like foods whose flavor is regarded as important or the like is described herein, in which a resin powder layer is formed on its inner surface and on the outer surface of its neck portion by electrostatic painting and thereafter it is finished by baking, whereby a resin coating film that is free from pin holes and has a strong corrosion resistance can be formed. Also a novel apparatus for forming a resin powder layer for such metallic squeeze-out tube is described, in which a cylindrical high voltage electrode is disposed in the proximity of an outer surface of a neck portion of an unprocessed metallic squeeze-out tube, a rod-shaped electrode to be inserted concentrically to the interior of the neck portion is provided if the inner diameter of the neck portion is large, a cylindrical high voltage electrode that is vertically movable and adapted to eject resin powder is disposed in the interior of the body portion of the squeeze-out tube, and further, air flows at the various portions in the metallic squeeze-out tube are adjusted so as to continuously form a powder layer.

    Abstract: Apparatus for powder coating the inside of can bodies, either along a strip or completely, comprises a spray head having an inlet opening fed through a gun with a powder-air mixture and an exit opening located so as to deliver the powder-air stream transversely to the gun axis onto the can body. The exit opening is either a slot-type nozzle for applying a strip, or an annular opening for a complete coating of the can. So as to apply the coating in a precisely limited form without rebound, insert baffles in the form of rods are fixed in the spray head passage which expands between the entry and exit openings to slow down, distribute and orient the powder-air stream towards the exit opening. A deflector wall is located at the end of the passage to deflect the powder-air stream towards the exit opening. Where the slot-type nozzle is used, the powder-air stream may enter an antichamber having an outlet slot parallel to the nozzle and a further slot opening into the passage beyond the antichamber to be deflected into the portion of the nozzle beyond the antichamber by a series of inclined deflector walls. A separate stream of air, separate from the powder-air stream, may be fed into the passage beneath these deflector walls.

    Abstract: A METHOD FOR COATING THE INNER SURFACE OF A METAL PIPE HAVING AN INNER DIAMETER OF 2 TO 15CM. IS CHARACTERIZED BY HEATING SAID METAL PIPE ELECTRICALLY GROUNDED AT A TEMPERATURE OF FROM A SOFTENING POINT OF A COATING COMPOSITION TO BELOW A MELTING POINT THEREOF, FEEDING NEGATIVE CHARGED DRY PARTICLE OF A COATING COMPOSITION INTO THE INTERIOR OF SAI METAL PIPE FROM ONE END OF THE PIPE AND SUCKING AIR AT THE SAME TIME FROM THE OTHER END OF THE METAL PIPE SO AS TO FORM AN AIR STREAM CARRYING THE PARTICLES AND TO ALLOW THE PATICLES TO DEPOSIT ELECTROSTATICALLY ON THE INNER SURFACE OF THE PIPE.
