Each roll is driven by its own servo motor for precise tension control with independent contact control for controlling roll density. The shaftless winding technology provides high speed unloading of the rolls either manually or, for larger rolls, directly onto roll carts. All models can be supplied with automatic knife positioning and powered or automatic arm positioning to improve productivity. The touch screen operator interface has simple recipe systems for multiple material types and slitting parameters.
