Abstract
A method for manufacturing a slip-ring element having contact rings includes the following steps: machining and/or coating lateral sides of the contact rings; mounting the individual contact rings side-by-side, so that they touch each other at the end face; at least partially filling the inner space formed by the side-by-side-mounted contact rings with an adhesive agent, so that the side-by-side-mounted contact rings are cemented to each other after the adhesive agent has hardened; and complete removal of material from the contact rings in the region where they touch at the end face, so that a peripheral, electrically insulating recess is produced along a circumferential line.
