ABSTRACT:
For manufacturing a winding protection for tape-wound cores that are surrounded with a winding, a polymer film is provided that is deposited onto the tape-wound cores from a vapor phase at room temperature in a drum process. Due to the end face penetration of the polymer into the tape-wound cores, the polymer is solidified and simultaneously surrounds all sides with a thin, uniformly adhering and directly windable layer.
