• the cable coil is wrapped N times at one or more points with a tape, preferably an adhesive tape, to prevent the cable coil from falling apart into its individual windings and thus becoming unmanageable in subsequent production steps.
• a tape preferably an adhesive tape
• this process is preferably carried out using automated tying.
• Automated tying machines generally have a high degree of autonomy, i.e., the storage or spool capacity of the adhesive tape is approximately 20–500 m, so that downtime of the tying machines is only necessary at long intervals.
• Such fully automated tying machines can be used both in stationary applications, i.e., permanently mounted in a system, or in mobile applications, for example, as part of a robotic end effector. A trend for future applications is toward shorter processing times for each cable coil.

• the binder not according to the invention has at least the advantage that the free end of the strip section can be optimally positioned to ensure immediate adhesion between the strip section and the cable coil, and to begin tying as soon as the cable coil is inserted into the gap. This shortens the tying time and cycle times at the binder. In particular, so-called main times, i.e., the time a cable coil spends at the binder, are reduced.
• the arrangement of the coil body offset from the longitudinal axis of the gap enables the alignment of the free end of the strip section transversely. to the gap.
• the strip section for tying off the cable coil has a predetermined length. The length can be freely selected by winding it onto the coil body.
• the respective strip section is separated from the strip and can be used in its entirety for tying.
• the separation of strip and strip section as well as the winding up take place during off-peak times, i.e. at times when no cable coil is being processed at the tying device, so that subsequent tying can begin and be carried out immediately when a cable coil is inserted into the gap. This shortens cycle times of the tying device.
