Tensioncontrol

Fortherotarymachine,thetensioncontrolisveryimportant,mainlyreflectedinthefollowingpoints:

1,itisthehigh-speedrotationoftherotarymachinepremise.

2.Avoidoverloadcausedbyexcessivetension,therebyprotectingmachineparts.

3.Avoidlooseandpoorqualitywinding.

4.Reducethefractureofthesubstrate(thefractureofthesubstratecausesthelossofmaterialandtime,andmayalsodamagetheknife).

5.Preventcurling,especiallyforcompositematerials.
