Textile Cord Calendering Line

Textile Cord Calendering Line

Application
For rubberizing two-side of textile

Scope
Φ610X1730/Φ700X1800

Product Features

  • Small L/D ratio of rolls, enables small deformation in the action of the same calendering strength.
  • The roll surface and shaft journal are clamped and grinded on high precise CNC grinder, which enable roller with micron geometric tolerance.
  • The calender frame is casted with nodular cast iron, of high rigid and shock absorption.
  • The left/ right frame is processed and molding for once on CNC boring lathe, which ensures both frame the consistence of dimension.
  • Double row cylinder roller bearings of high precise are used to support the calender roll, which possess higher precise of rotation by contrast with self-aligning roller bearing.
  • Pre-bending systems are amounted at Roller#1,#3,#4, which keeps machine stable and the product with high precision.
  • inside gearbox. All the surfaces of gears are machined by grinder (made by Niles Germany) and of high precision. Rolls are kept in steady speed when rotating.
  • Encoder of high precision is adopted for detecting motor speed of roll. Speed closed-loop control system keeps roll hard mechanical property while enlarging load.
  • Fixed conveying belt from two roll mill to wig-wag feeding device is supplied by DXS, which will shorten customer design & purchase period for auxiliary equipment.
