The doffer is driven by and electronic frequency converter and toothed belt, so as to its speed variation is stepless.
The web take-off unit allow visual inspection of the web, its ensures the web delivering in high speed and running very stable. The calendar roller specially designed is the function of measuring roller for the auto leveler.
There are one imported PLC and two imported inverters in the electronic control cabinet of card FA204. It controls doffer’s and feed motor’s speed to make a stepless variable-speed and run it at the rate, with a smooth speed up and down and a good brake performance, it is running steady and reliably. It is up user if the machine is equipped with an auto leveler. The imported display screen is erected on safety cover in the left front of machine. It can control each motor. It can display all data on dynamic technology and take an alarm for all faults and full-can status. Control center of whole machine is a imported programmable controller which operates simply and reliably.
