Abstract

L'invention porte sur un dispositif d'alimentation (10) qui possède un magasin (11), un dispositif de manutention par dépression (15) et une brosse (13). Le magasin (11) reçoit des électrodes en forme de plaque empilées (20) et présente une ouverture (11a) sur l'extrémité supérieure. Le dispositif de manutention par dépression (15) saisit par plateau de maintien à vide les électrodes (20) et les retire à travers l'ouverture (11a). La brosse (13) vient en contact avec le bord externe des électrodes (20). Le dispositif de manutention par dépression (15) élève et abaisse les électrodes saisies par plateau de maintien à vide (20) une pluralité de fois, et frotte par conséquent le bord externe des électrodes (20) contre la brosse. Des paires d'électrodes (20) adhérant étroitement sont par conséquent séparées, et des électrodes uniques (20) peuvent être retirées par le plateau de maintien à vide (15). En même temps, des bavures sur le bord externe de l'électrode (20) sont éliminées par frottement par la brosse (13).
