VFD in wire and cable industry
The pay-off speed is depend on the take-up speed. Take-up wheel always experiences process of starting and slow-down to stop, which brings the pay-off wheel a non-constant speed. Meantime, wire and cable always change on the wheels. When the rotate speed is stable, the linear velocity is constantly changing. The take-up tension impacts the quality of the product directly. If the tension too large, the wire will be took-up too tightly. Slim wire is easy distorted and the inner filament is easy to be break. If the tension is too small, the take-up wheel will axially slip and dislocate while take-up the wire. The wire can’t be took-up tidily. So pay-off wheel have to adjust the speed of itself according to the balance position of the tension balance bar.
