Davis-Standard’s new SLC (Sliding Carriage) surface winder for blown film employs pneumatics instead of hydraulics for controlling the winding force and is capable of wound roll diameters up to 1,500mm. It is available in widths from 1,118-3,400mm and will wind rolls on 75 or 150mm cores.
The AC-driven winder offers several special features for improved performance. The weight of the roll is supported by bearings located close to the wound roll edge and supported on a horizontal linear rail for greater shaft performance. The winding force is controlled via pneumatic cylinders with control feedback and taper capabilities.
The finished roll unloading system is independent from the winding transfer cycle sequence shortening and streamlining new roll changes. Roll carts and shaft handling are available to add automation to fit each plant’s needs.
