A method for producing transformer cores that are made of a plurality of stacked sheets, the sheets being continuously unwound from a supply roll, being subsequently cut to length and into shape, being conveyed on a transport belt system after cutting and being stacked onto a stacking table, characterized by the following method steps: a) in at least two stacking stations arranged one behind the other in the conveying direction (a) of the sheets (2 - 6), at first, one sheet of one limb side (2 or 4) of the transformer core is placed on each of the stacking tables and one sheet of a yoke side (5 or 6) of the transformer core is placed on support tables alternately, or a plurality of sheets of one limb side (2 or 4) of the transformer core is stacked on the stacking tables and a plurality of sheets of a yoke side (5 or 6) of the transformer core is stacked on support tables alternately; b) after lateral displacement of the stacking tables, one sheet of the other limb side (4 or 2) of the transformer core is placed on each of the stacking tables and one sheet of the other yoke side (6 or 5) of the transformer core is placed in receiving devices alternately, or a plurality of sheets of the other limb side (4 or 2) of the transformer core is stacked on the stacking tables and a plurality of sheets of the other yoke side (6 or 5) of the transformer core is stacked in receiving devices alternately; c) after further lateral displacement of the stacking tables, one sheet of the middle limb of the transformer core is placed or a plurality of sheets of the middle limb of the transformer core is stacked on each of said stacking tables alternately, handling systems simultaneously turning the sheets of the one yoke side (6 or 5) or the packets of sheets of the one yoke side (6 or 5) with the longitudinal direction of the yoke side into the rectangular position toward the conveying direction (a); d) then, the handling systems place, on the stacking tables, the sheets of the one yoke side (6 or 5) or the packets of sheets of the one yoke side (6 or 5) with their ends at the one ends of the sheets of the limb sides (2, 4) of the corresponding stacking table and with their center at the one end of the sheets of the middle limb of the corresponding stacking table or with their ends at the one ends of the packets of sheets of the limb sides (2, 4) of the corresponding stacking table and with their center at the one end of the packets of sheets of the middle limb of the respective stacking table; e) the method steps a - d are repeated until the total height of the respective transformer core is reached. a) in at least two stacking stations arranged one behind the other in the conveying direction (a) of the sheets (2 - 6), at first, one sheet of one limb side (2 or 4) of the transformer core is placed on each of the stacking tables and one sheet of a yoke side (5 or 6) of the transformer core is placed on support tables alternately, or a plurality of sheets of one limb side (2 or 4) of the transformer core is stacked on the stacking tables and a plurality of sheets of a yoke side (5 or 6) of the transformer core is stacked on support tables alternately; b) after lateral displacement of the stacking tables, one sheet of the other limb side (4 or 2) of the transformer core is placed on each of the stacking tables and one sheet of the other yoke side (6 or 5) of the transformer core is placed in receiving devices alternately, or a plurality of sheets of the other limb side (4 or 2) of the transformer core is stacked on the stacking tables and a plurality of sheets of the other yoke side (6 or 5) of the transformer core is stacked in receiving devices alternately; c) after further lateral displacement of the stacking tables, one sheet of the middle limb of the transformer core is placed or a plurality of sheets of the middle limb of the transformer core is stacked on each of said stacking tables alternately, handling systems simultaneously turning the sheets of the one yoke side (6 or 5) or the packets of sheets of the one yoke side (6 or 5) with the longitudinal direction of the yoke side into the rectangular position toward the conveying direction (a); d) then, the handling systems place, on the stacking tables, the sheets of the one yoke side (6 or 5) or the packets of sheets of the one yoke side (6 or 5) with their ends at the one ends of the sheets of the limb sides (2, 4) of the corresponding stacking table and with their center at the one end of the sheets of the middle limb of the corresponding stacking table or with their ends at the one ends of the packets of sheets of the limb sides (2, 4) of the corresponding stacking table and with their center at the one end of the packets of sheets of the middle limb of the respective stacking table; e) the method steps a - d are repeated until the total height of the respective transformer core is reached.
