Abstract (en)

[origin: WO2020176916A1] The invention relates to a method and a forming and inserting unit (24) for creating a conductor stack (6) for insertion into a lamination stack (1), the conductor stack comprising at least one conductor element group (7, 8, 9) composed of a plurality of conductor elements (10, 11, 12). The conductor elements (10, 11, 12) are inserted into a forming and inserting tool (25) in receiving grooves (30, 32) provided therein and defined by retaining elements (29, 31), and are held in position in said receiving grooves. Subsequently, the forming process of the conductor elements (10, 11, 12) is carried out. The formed conductor elements (10, 11, 12) are still held in position by an inner tool (27) and an outer tool (26) of the forming and inserting tool (25) and are inserted into the lamination stack (1) directly by means of said inner tool and outer tool.
