Gassing axis slip shaft with common difference

Ordinary its structural expansion gassing axis tile for a strip axis, no section, so no slip function, to cut more than with the material changes the tension of the corresponding slip action, or material thickness uneven tension change when prone to winding not neat, break, loose roll, roll off phenomenon, thereby causing loss to the material. Winding speed is low, the efficiency difference of the same shaft can't charge volume size.
