Abstract (en)

1. A device for obtaining the coating on a continuous basis of the external surface of a section (2) with a substantially constant cross section, in particular a closed one such as a pipe, by means of a liquid product, comprising means (3) for causing the section to advance along a longitudinal feeding motion through a coating tank (9) comprising an inlet opening provided with a leak proof seal (14) and an outlet opening provided with a semi-leak proof seal (18) capable of being traversed by the section, characterized in that the semi-leak proof seal (18) is, on the internal side of the coating tank, entirely immersed in the liquid product and that it is formed by a hollow tubing (19) of an expanding material and filled by a fluid under with a density close to that of the said liquid product.

Abstract (fr)

Procédé et dispositif pour revêtir en continu la surface externe d'un profilé (2) à profil sensiblement constant, notamment fermé tel qu'un tube, à l'aide d'un produit liquide. On fait défiler le profilé selon un mouvement d'avance longitudinal (3), on l'enduit en formant en un point du parcours (5) du profilé un anneau de produit liquide en contact avec la surface à revêtir et on fait passer le profilé, en aval de ce point, à travers un joint semi-étanche (5).
