Machine Control

Optima rewinder is designed for:  

  • Limited time for finished roll changing
  • Automatic shaft handling
  • Limited manual operation 
  • Machine safety designed/approach 
  • Machine friendly operator

Tension Control for rewinders

OPTIMA’s improved Tension Control System avoidselongation of the nonwovens passing through the web routing. The system checks the roll phase by time unit. It allows a perfect speed control also during machine acceleration and deceleration.

NIP Control for rewinders

OPTIMA Closed Loop Hydraulic System

The sensors installed on the machine send continuous feedback to the control system, which makes sure that the NIP of the wound reel is detected and adjusted in real time.

The reel growing follows the parameters of the signals coming from the sensors. In case that the NIP set is not correct according the paper characteristics, the NIP increases or decreases dramatically.

OPTIMA automatically corrects the values, without operator intervention, restoring the control balance. 

The control works on thickness preservation and on the finished reel density.
