ABSTRACT:
Hollow bodies, e.g. pipes, are coated with protective layers of a liquid or pulverulent material by electrostatic spraying and hardening in which the bodies are disposed horizontally and parallel to one another upon a chain conveyor and are automatically displaced transverse to their longitudinal axes. In a first stage the coating is provided on the hollow bodies exclusively of their end regions and in a second stage the coatings are applied to the end regions.
