1. An apparatus for manufacturing an at least partial nest of pin conductors for forming a stator, the apparatus comprising a stator core template, wherein:
the stator core template comprises a block body provided with radially extending ribs, said ribs forming slots therebetween for insertion of legs of the pin conductors;
the apparatus further comprises at least one ring element arranged to provide an outer radial abutment face for inserted pin conductors; and
at least an upper part of the ribs has a radial length which is larger than the radial length of a lower part of the ribs, the ribs comprising a continuous transition between the upper part and the lower part.
