1. A cylindrical battery winding apparatus, comprising:
a pair of separator unwinding parts (10) that unwind separators from separator rolls (11) to separate a positive electrode material and a negative electrode material;
a pair of alignment parts (20) including grippers (21) that pull and align one end of the positive electrode material and the negative electrode material respectively cut to a predetermined length;
a winding part (30) that stacks the positive electrode material, a separator and the negative electrode material and winds the stacked the positive electrode material, the separator and the negative electrode material to form a jelly roll; and
a cutting part (40) that cuts the separator and cuts a fixing tape to secure the jelly roll.
