摘要： A recoiling facility for a magnesium alloy sheet (S) is provided with: an unwinder (1) which is able to unwind a coil material (C) formed by winding magnesium alloy onto a fixed mandrel; a heating furnace (4) which heats to a predetermined temperature the magnesium alloy sheet (S) which has been unwound from the coil material (C); a trimmer (2) which trims both side edges of the sheet; and a winder (3) which rewinds the magnesium alloy sheet (S). According to the present invention, it is possible to rewind a coil material formed by winding a magnesium alloy sheet onto a fixed mandrel and remove the fixed mandrel, and to perform leveling and trimming on crack portions and shape defect portions in width end portions of a plate that have been generated by multi-pass rolling so as to manufacture a high-quality product coil.
