1. A component for an electric machine, comprising:
a flat region in which an electric line runs when the component is integrated into the electric machine and which includes a sharp-edged structure; and
a polymer layer adhering to the flat region without further aid such as to mask the sharp-edged structure and thereby protect from damage the electric line on the flat region, said polymer layer being made of cured plastic adhesive and jetted onto the flat region in the form of threads, such that the threads are spin-coated on top of one another in the form of overlapping loops and form a network structure which spans the sharp-edged structure.
