1. A method for producing slot insulators for winding slots of a component of an electrical machine, method comprising steps of:
a) supplying a strip of insulating material,
c) cutting off one or several insulator strip portions from the strip,
d) molding the cut insulator strip portion for one of the winding slots to a shape of the winding slot in a respective one of several molds, and
e) inserting the molded insulator strip portion into a different winding slot,
wherein at least the steps d) and e) are carried out simultaneously for at least two insulator strip portions to be inserted into different winding slots such that step d) is carried out for a second insulator strip portion in another one of the several molds, while step e) is carried out for a previously molded first insulator strip portion simultaneously.
