The harm of static electricity to the film slitting machine during winding

As the speed of the slitting machine becomes faster and faster, the strong friction between the insulating polymer film material and the rubber roller and the metal roller during the slitting process will generate a lot of static electricity, which will easily attract dust to the material and affect the quality of the film roll. , especially on the pattern of some printed films.
The mutual attraction and repulsion between static electricity will cause relative displacement between the film layers, resulting in a series of winding problems such as slippage, slitting offset, tension change and so on. What's more, serious friction will generate an ultra-high potential of hundreds of thousands of volts, which may cause air discharge and directly cause a fire, or electric shock to the operator, resulting in injury accidents.
