摘要

Process for applying a continuous coating layer, of a practically uniform thickness, on a core or support, characterized in that a coating composition in the fluid state and practically devoid of bubbles, is forced with impulsion and under pressure higher than atmospheric at uniform speed in the form of a radial current towards the center concentrically around said support while the latter moves at a uniform speed in the direction of its longitudinal axis and because said impulsion and said pressure above the atmospheric pressure stop exactly before the radial current of the coating composition is contacted with the support to be coated, which then the coating composition solidifies.
