Up to 26,000 RPM and thread temperatures up to 200 C.
In many instances the S-GVR roll has been able to replace much
more expensive air bearing separator rolls.
F&T Separator rolls are used for the drawing process on draw-twisting, winding and texturing machines. And our separator rolls have been already supplied in large quantities to machine builders and man-made fiber plants world-wide.
Working surface of the shell (roll) is plated with hard-chromes to guard the surface from abrasion and grooving by the filament. The surface with “orange skin effect” provides the most suitable frictional condition, so that the filament is reliably guided.
Ceramic coating is also available.
Ceramic coating produces nodular surfaces with larger and harder modules than hard chrome plating. The very harder nodules make the service life of the surface three to ten times longer than hard chrome plating.
Ball bearing with a plastic ball retainer is used for NSD series, except for hot drawing, to make the rotating torque as small and the operating as uniform as possible. For NUM series, newly-developed integrated Bearing Unit is installed. This remarkable design makes the roll more rigidity, higher load capacity and higher speed. Furthermore, the bearing unit is detachable from the shell (roll).
For normal (cold) drawing use Kluber super LDS 18
For Hot drawing use Kluber Isoflex Unisilikon TK44NO. Kluber Topas NB52, Dow coning 44
F&T separator rolls are manufactured in various designs and dimensions. If you do not see the roll you need feel free to contact us for your special requirements.
