Low-Tension Winding Function

Controlled winding torque for sensitive slit rolls.

Suitable for stretch-sensitive films, thin PET film, electronic film and lithium battery-related separator film applications where low starting tension is required.

  • Center-air-pressure slip shaft structure designed for low starting tension.
  • Suitable for stretch-sensitive film slitting and lithium battery film slitting.
  • Supports very low starting air pressure where light winding force is required.

  • The ring is built from roller positioning balls and bearings.
  • 3-inch ring outside diameter is 75.5 mm, expanding to 77.8 mm at the highest point.
  • Suitable core inner diameter is 76.2 +/- 0.2 mm for rubber, aluminum or paper cores.
  • Standard widths include 10, 15, 20, 25, 30 and 35 mm; other widths can be designed to order.
  • Standard inner diameter is 50 mm.

Selection Notes

Confirm core material, core inner diameter, required width, winding tension range, shaft structure and whether the application needs low starting tension or higher roll-holding force.

Technical Reference Data

Pull force reference values for preliminary selection.

Reference values should be confirmed according to the actual shaft structure, ring width, groove material and air path before final selection.
