1. A method for introducing insulated winding packets into stator or rotor grooves, comprising the following method steps:
inserting insulating layers into transfer grooves of a transfer tool, wherein each of the insulating layers includes sections and at least one section of each of the insulating layers lies radially outside of a respective transfer groove;
transferring wire webs of the winding packets into the transfer grooves;
closing the insulating layers by folding the sections in a direction of the wire webs of the winding packets and fixing the sections in a folded position to form folded sections of the insulating layers; and
inserting the winding packets into a respective stator or rotor groove such that the folded sections are arranged between groove bases of the stator or rotor grooves and the wire webs of the winding packets.
