  • Patent number: 4612107
    Abstract: A device for holding hollow bodies of electrically conductive material, such as cans of sheet metal, while they are conveyed through an electrophoretic dip bath, is provided with a conveying element which runs through the dip bath, which seizes in succession the open ends of the individual hollow bodies and temporarily holds them. For this purpose, at least three electrically conductive holders for the individual hollow bodies are arranged on the conveying element, which holders are rotatable about a shaft and form gripping devices for seizing, in a detachable manner, the edge of a respective hollow body. The holders are preferably conical pegs, on the surface of the sheath of which threads are arranged as gripping devices, which threads are interrupted at at least one point.
