1. An apparatus for manufacturing a stator with a plurality of hairpin conductors arranged in slots of a stator core, the apparatus comprising:
a stator core template comprising a body having a closed annular shape which is provided with a number of radially and axially extending slots corresponding to the number of slots of the stator core, said slots of the stator core template having at least one of a circumferential width larger than the circumferential width of the slots of the stator core or a radial length larger than the radial length of the slots of the stator core;
an insertion station for inserting at least one hairpin conductor into at least one of said slots of the stator core template such that said hairpin conductor is arranged at a first position within said slot, wherein in said first position the hairpin conductor is arranged differently than in an intended position in the stator core; and
a moving station for moving said hairpin conductor within said slot of said stator core template from said first position to a second position.
