Individual Arm Slitter Rewinders
The ALPHAWIND individual arm centre and centre surface winders provide the ultimate in winding of sensitive and thin films.
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.
Examples shown:
- ALPHAWIND C300 with integrated unwind for clean room operation. Shaftless unwind with roll lift picks roll directly from floor or roll cart.
- Precision winding head with constant geometry ultralow friction layon assembly for sensitive laminates.
- ALPHAWIND 1000 heavy duty centre winder with overhead web path for coated papers and films.
