Therefore, when a bottom drum 10 has rolled up a roll of trimming waste 13 of the electrostatic film, the cutting assembly 1 will cut the electrostatic film, and then the lateral moving mechanism 6 is started to move the moving frame 8, so that the next bottom drum 10 is aligned with the trimming waste 13, and then the trimming waste 13 is wound in the bottom drum 10. Therefore, after five rolls of trimming waste 13 are wound up, the five rolls of trimming waste 13 can be taken out at the same time by removing the winding roller 12.
