A shrink sleeve film is unwinded on a cross-cutting machine and then cross-cut. The cross-cut films are deposited in a shingle on a conveyor belt. Small film packets are then formed from the scale by hand. The packets are placed in a box.
The cross-cut shrink sleeves are highly electrostatically charged. When a cross-cut sleeve was placed on the conveyor, it stuck to the guide rollers. The shingle could not be formed evenly on the conveyor belt. It was also not possible for the operator to remove the sleeves from the shingle and create small packs from them, as the films stuck together. Production was not possible due to the charge.
Suitable discharge bars were installed in an optimal position and with adapted discharge angle. The one-sided air support optimizes the process.

HIGH-END discharge for highest discharge performance The VARIO discharging bar flexBAR R60L with its free-standing, air-assisted spring tips has a very high passive discharge effect, which enables active operation even at low AC high voltage. To increase the range, a small amount of air optionally flows through the hollow spring tip. The air flow additionally serves the continuous cleaning of the emission tip.
The PRO IONIZER is a powerful and flexible device which is suitable for absolutely any application. With the new Performance Control, each discharging component can be supervised and displayed separately. With different adjustable process parameters and several interfaces the PRO IONIZER sets a new benchmark. Click here for more information!
