The invention relates to a contacting device for a galvanization apparatus (11), comprising contacting rollers (20) with a continuous rigid external face (26, 27) which is joined to a jacket section (22). The jacket section (22) is provided with an inner opening (23) that is wider than a rotating shaft (30) on which the contacting roller (20) sits. This allows the contacting roller (20) to be moved in a radial direction, electric contacting and securing of a basic position being obtained via springs (32). The movability of the contacting roller (20) ensures good contact as the contacting roller (20) rests against substrates (16) even when the substrates (16) are uneven. The contact pressure can be relatively small.

Selon l'invention, un dispositif d'établissement de contact destiné à un dispositif de dépôt électrolytique (11) présente des galets de contact (20) pourvus d'un côté extérieur (26, 27) rigide continu, ce côté étant relié à une section tubulaire (22). Cette section tubulaire (22) présente une ouverture intérieure (23) qui est plus large qu'un arbre rotatif (30) sur lequel est placé le galet de contact (20). Le galet de contact (20) est ainsi mobile dans le sens radial, un établissement de contact électrique et un blocage de la position dans une position de base étant obtenus par l'intermédiaire de ressorts (32). La mobilité garantit un établissement de contact satisfaisant par application sur des substrats (16), y compris lorsque ceux-ci présentent des aspérités, la force de pression pouvant être relativement faible.
