Abstract

The utility model relates to a symmetric double-shaft winder, which comprises a machine frame, wherein a group of first winding units and a group of second winding units which are relatively independent and a cut-off unit are arranged on the machine frame. Compared with a traditional symmetrical double-shaft winder, the symmetric double-shaft winder utilizes two groups of winding units which are controlled independently, when the previous group of winding units finish working, the next group of winding units can be independently controlled to lead a next winding shaft to contact with a unwound film at the tail end of the previous winding units and directly starts winding after the film is cut off by the cut-off unit, accordingly length of unwound material is greatly shortened, and waste material is reduced as much as possible. Winding units which do not finish winding can be driven by a turnover motor to rotate to a position where the material is convenient to be detached, so that an operator can smoothly remove wound material away from the winder, and reinstall the winding shaft for the next winding.
