Description

  1. Overview
    1. Dedicated to calendering of ribbon, woven mark, clothing, or special narrow fabric.
    2. Fabric calendering can produce different sheen results.
    3. Processing object: ribbon, narrow fabric, weaving trademark.
    4. Type: vertical 2-rollers, both heating mirror roller.
    5. Ribbon outlet type: with way to free fall.
    6. Nominal width: 300 mm (11.8 in).
    7. Max. processing quantity: 6.
    8. Speed: 5 to 40 m/min.
    9. Max. line-pressure: 330 N/mm, 9 t.
    10. Total power: 25 kW (33.5 hp).
    11. Dimension: 4300 mm (169.3 in) x 2500 mm (98.4 in) x 2200 mm (86.6 in).
  2. Calendering Roll Component Parameters
    1. Diameter of mirror roller: Ф260 mm.
    2. Material of mirror roller: alloy forged steel, ground to mirror surface (roughness ≤ 0.2 μm).
    3. Mirror roller cavity constructed with around-the-hole HTF loop, structure conducive to rapid heating.
    4. Bearing of rollers: 22218CA/W33 heavy bearing.
    5. Up and down roller gap adjustment range: 0 to 0.5 mm.
  3. Drive Control System
    1. Power of main motor: 2.2 kW (3.0 hp), driven with gear reducer.
