Pre-fitting nest and method for forming a crown from a plurality of u-shaped electrically conductive hairpins in order to then be able to install the crown in a machine element of an electric machine

A method for forming a crown from a plurality of U-shaped electrically conductive hairpins to then be able to install the crown in a machine element of an electric machine, comprising the steps of:

• providing a plurality of U-shaped electrically conductive hairpins;
• joining the hairpins by fitting the legs of the hairpins into an accommodating member, so that the hairpins together form a crown;
• wherein, when the respective hairpin is fitted into the accommodating member, a first leg of the hairpin is rotatably held in the accommodating member to position a second leg of the hairpin in the accommodating member by rotation about the first leg;
• then providing the crown of hairpins for introduction into a hairpin accommodating means of the machine element.
