A contacting device for a galvanization apparatus comprises contacting rollers with a continuous rigid external face, which is joined to a jacket section. The jacket section is provided with an inner opening that is wider than a rotating shaft on which the contacting roller sits. This allows the contacting roller to be moved in a radial direction, wherein electric contacting and securing of a basic position is obtained via springs in every one of the radially moved positions. The moveability of the contacting roller ensures good contact as the contacting roller rests against substrates also when the substrates are uneven. The contact pressure can be relatively small.
