Slitter rewinders are designed for high-precision slitting of isolation material in the process of rewinding. Finished product: rolls of the required width and defined layer density of the material. Application of rolls - insulating machines in cable production.

Machines options:

  • Fixation of unwind and rewind rolls by the expanding pneumatic shafts
  • Edge tracking system with automatic correction
  • Noncontact transducer from accidental start if the unwind shaft is unfixed
  • Automatic pneumatic disk braking system of the unwind roll
  • Automatic control of material tension
  • Constant slitting speed mode
  • Rewind density control system
  • Individual translucent lighting
  • Unwind and rewind roll diameter sensor
  • Rewind material length meter
  • AC servomotor to spin the slitting roll
  • Male/female knife
  • Individual asynchronous servomotors for each take up and intermediate shaft
  • Automatic control of the material disruption with auto-stop function
  • Graphical control panel
  • Scrap removal operations
  • Two control panels (unwind and rewind)

The machines are divided into types according materials and capacity.
