Abstract: The invention relates to a holder to be used during the stripping of a metal deposit produced on the surface of a mother plate in electrolytic refining, which mother plate has a supporting bar (12) fixed at one edge of the plate for supporting the mother plate during the stripping (16), and an edge strip (10) at least on the edge opposite to where the supporting bar (12) is fixed. According to the invention the holder (1) has at least one pressing member (4), so that during the stripping (16) the metal deposit (15) is pressed by the pressing member (4) in order to make a contact between the deposit (15) and the pressing member (4) close to the edge strip (10) installed on the edge opposite to where the supporting bar (12) is fixed.

Abstract: An arrangement for conveying plates (4) in particular mother plates with or without a deposited metal layer, in an electrolytic metal refining plant, wherein the plates are intended to be conveyed in the conveyor arrangement (25, 50) along at least one horizontal conveyor path with the plates orientated generally vertical and equidistant from one another therealong, characterized in that the conveyor arrangement is of the walking beam kind and includes fixed supports (28, 54) and at least one walking beam (30, 62) having movable supports (31, 67), wherein the walking beam is arranged to move in a cyclic pattern, including a lifting movement in which all the plates conveyed along the path are lifted by the movable supports from their fixed supports in a first position, a forward movement in which all plates are advanced simultaneously one step while resting on their movable supports, a lowering movement in which the plates are placed on fixed supports in a new, second position, and a return movement, wherein t
