- the splicing operation may be performed manually or automatically. For example, in the case of exchanging the old electrode roll and the new electrode roll on one unwinder, stop the operation of the equipment and scan the barcode of the new electrode roll with the barcode reader installed in the unwinder to manage the production of information on the new electrode roll. It can be transmitted to the system (MES), etc.

It should be noted that the electrode coordinate value is the signal value of the encoder, not the actual position of the actual electrode when the electrode is actually broken. That is, for example, when the tension sensor 20A detects a sharp decrease in tension, the tension sensor may interlock with the position measuring device to acquire the electrode coordinate values at that time.
- the electrode coordinates at that point are the electrode break point even if the tension has decreased rapidly, and there is usually a time difference between the sensing of the tension sensor and the point at which the actually broken electrode reaches the tension sensor due to electrode travel. .
