ABSTRACT:
Collars for surrounding the nipples of an anode bar are produced from a coil of aluminium sheet material. Sheet metal strips are separated from the coil, and are then pre-shaped to substantially U-shaped parts in a bending unit. These U-shaped parts are then pushed over the nipples of the anode bar, and their overlapping ends are fixed to one another by means of a fixing device, to form closed collars.
