The motor 802 is programmed through the PLC according to the diameter of the rolled sheet 4. When the rolled sheet 4 is unrolled, the guide roller 501 can move up and down in the limit column 5. The uncoiler 2 drives the rotating shaft 201 to rotate, and the rotating shaft 201 drives the rolled sheet 4 to rotate. The rolled sheet 4 is naturally unfolded due to the rotation, and the unfolded sheet is overlapped to the next process. The guide roller 501 performs the lowest top to the sheet.
