Title:
DEVICE AND METHOD FOR ELECTRICALLY CONTACTING TREATMENT MATERIAL IN ELECTROPLATING SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2011/066824
Kind Code:
A8
Abstract:
The invention relates to the electrical contacting of band-shaped or plate-shaped material (1), which can be conveyed through an electroplating system on a transport track. The cathodically polarized contact means (6) are located, for example, on the underside of the material (1) in the electrolyte (12), which is circulated in the electroplating system. The material is electrically contacted in order to transfer current to the material (1). In the prior art, the contact means (6) are metal-coated in addition to the material (1). Said metal coating must be continuously removed from the contacts. According to the invention, each for example tubular contact means (6) is cooled by means of a cooling unit or a cooling medium. No metal is deposited on the cooled surface of the contact means (6) if the temperature difference between the working temperature of the electrolyte (12) and the surface temperature of the contact means (6) is sufficiently large. This property can be supplemented with a surface of the contact means (6) that cannot be cathodically metal-coated in the electrolyte (12) used.
