The present invention relates to a plating method and apparatus in which an
object
to be coated is immersed in a bath in a basin and a plating tool which is kept
permanently in the basin in the vicinity of a pipe or duct passing through the
basin,
where the object to be coated is not placed in conjunction with the tool until
inside
the bath. In the plating method of the present invention, a current is
supplied to
anodes by means of a conductor rail, which is located in the pipe in the basin
which
the electrolytic liquid surrounds and which extends above the liquid surface
where
the object to be coated is immersed in the basin by means of a suspender
supported
on the upper end of the pipe.
La présente invention se rapporte à une méthode et à un appareillage d'électrodéposition dans lequel un objet à plaquer est immergé dans un bain de bassin et où un outil d'électrodéposition, est laissé en permanence dans le bassin, à proximité d'une canalisation traversant le bassin. L'objet à plaquer n'est pas placé conjointement avec l'outil, tant qu'il n'est pas dans le bain. Dans la méthode d'électrodéposition de la présente invention, un courant est appliqué aux anodes au moyen d'un rail conducteur. Ce rail se trouve dans la canalisation du bassin entouré par l'électrolyte liquide, et qui occupe le dessus de la surface du liquide où l'objet à plaquer est immergé dans le bassin par un moyen de suspension supporté par l'extrémité supérieure de la canalisation.
