New Blown Film Surface Winder for Large Roll Diameters

(Somerville, N.J.)--Davis-Standard, LLC has introduced a new series of surface winders
for blown film processors to complement the successful PAC series. The new SLC (SLiding
Carriage) Series employs pneumatics instead of hydraulics for controlling the winding force.
Like the PAC series, the SLC Series is capable of wound roll diameters up to 60 inches
(1,500mm). The winder is available in widths from 44 to 134 inches (1,118 to 3,400mm) and
capable of winding rolls on 3-inch (75mm) or 6-inch (150mm) cores. This winder is the latest
addition to the company’s successful and broad range of surface and center winders.
This AC-driven winder offers several unique engineering 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.
Other features include a horizontal flat bed design, high capacity shaft bearings, highspeed
pneumatic traversing knife assembly, web tension control, touch screen controls for
winder settings, and two center slitters for multiple lane production. Options include additional
slitters, a center drive feature, gap winding, shaft accelerator, cord expander roll and shaft
extractor/cart.
