A method for straightening an anode provided with lugs and for eliminating casting fins thereon which anode is on its way to an apparatus for electrolytic refining of metals, comprising the steps of:
- placing an anode in a vertical position;
- providing a vertically oriented uniform stopping member which corresponds to the anode in configuration and has an opening in the middle thereof;
- providing a vertical oriented pressing means formed of several independent pressing members and placing said vertically oriented pressing means in opposition to the vertically oriented uniform stopping member;
- positioning said vertically oriented uniform stopping member and said vertically oriented pressing means in a vertical position;
- compressing the anode at several spot areas between the vertically oriented uniform stopping member and said independent pressing members of said vertically oriented pressing means for evening out the anode by simultaneously directing the compression at the several spot areas;
- directing a separate compression towards each edge of the lugs;
- and
- providing at least one actuating cylinder for each said independent pressing member.
