For example, an electrical plug connection is attached to the cable end, the wound coil being transported to a crimping press and at least the trailing cable end being fed to the crimping press. The additional holding of the cable with the first holding unit stabilizes the reel after the cable has been wound up, since the trailing cable end is prevented from slipping in the reel after it has been wound up.
