8. Fabric take-down system
In principle of the take-down tension strength must be small and
average. The take-down system is controlled by torque motor. There are
two important things to adjust the take-down tension strength.
First method is the two speeds No.1 and No.2 as Fig.8.1 adjust each
with turning knob and set the speed, the tension strength is larger and
the speed is faster. You input the numeric in program to select the speed
you want.
Second method is the roller. Each roller can be adjusted individually.
The pressure of roller gets larger and the speed of fabric take-down gets
faster.
☉
To detect fabric falling or wraparound, there is equipped with a
press-off detector in the front of roller and a fabric roll-up detector in
the back of roller. The machine will stop automatically when the fabric
happens fall or wraparound.
