L'invention a pour objet un dispositif de pelage de métal déposé par voie galvanique et un procédé de pelage de métal déposé par voie galvanique permettant de réduire la présence de bruit lors du pelage de métal déposé par voie galvanique et d'apporter silencieusement le métal déposé par voie galvanique pelé vers un processus subséquent. Le dispositif de pelage de métal déposé par voie galvanique permet le pelage de deux métaux déposés par voie galvanique associés ou de deux métaux déposés par voie galvanique séparés, qui ont été déposés par voie galvanique sur les deux surfaces d'une plaque cathodique, de la plaque cathodique par affinage électrolytique, le dispositif étant doté de : des dispositifs support supérieurs ; des dispositifs support inférieurs ; des dispositifs de martelage ; des dispositifs de flexion ; des dispositifs d'entraînement de coin disposés afin de permettre un mouvement de rotation et un mouvement vertical ; au moins un dispositif de décharge de presse à rouleaux ; et un carter, dont l'orientation peut être changée. La plaque cathodique est martelée par les dispositifs de martelage, les métaux déposés par dépôt voie galvanique sont cintrés par les dispositifs de flexion, les métaux déposés par voie galvanique sont pelés par les dispositifs d'entraînement de coin et les métaux déposés par voie galvanique pelés sont stockés dans le carter en dessous.
