10、y possible internal short Then the prepared nickel tab is riveted on anode and pat plain. We also tape the rivet section to prevent any possible internal short And finally, we clean the finished electrodes with vacuum and brushJelly rollThis is Jelly roll, a manual winding process In the course of J

11、elly roll, firstly, we place the separator in between central pins, press the foot switch to turn central pins about 120 degrees Secondly, place the anode to the edge of central pins, and turn central pins about 180 degrees Lastly, place the cathode to the edge of central pins During the winding pro

12、cess, we apply tension by pressing the electrodes and the separator We put the termination tape at the endAfter Jelly roll, we check the short circuit, then form the Jelly roll by pressing, so that it is easier to insert the Jelly roll into the can.Control points:1. When winding to the end of the an

13、ode, covering the anode completely by the separator.2. In the whole process, it is the most important points to ensure the best alignment among the cathode, the anode and the separator for the Jelly roll. The separator has to cover the anode and the cathode, and the anode has to cover the cathode co

14、mpletely. These points are mainly checked before short checkingVocabulary:Taping&insertingPut the tape on the two side of J/R, To prevent J/R being hurt in the insertion process.Put a piece of tape between cathode tab and J/R Because anode electrode is wider thancathode electrodePut the bottom tapeI
