Electrostatic surface charging is a frequent situation in covering and joining machines which operates in high speeds. This static charge should be neuralized before two plastic films are joined. In addition, filth and dust that sticks to surface will lead to printing faults and losses. During wrapping of joined two films in rolls static charge is generated because of friction.

Anti-static bar is placed heading to film surfaces, before joining to neutralize static charge in enviroment. Thus a correct neutralization is provided before joining.After that joined film is passed from anti static bar again to carry out correct wrapping. As a result a reliable production is obtained.
