Option 3: Two Charging Bars
In
Figure 4
, one charging bar faces another of
opposite polarity in an application where decorative
sheets are pinned to both sides of heavy particle board
prior to laminating. As the materials move between
the charging bars, the opposite polarity ions created
by each bar are driven toward each other by an
electric field formed between them. The decorative
sheets block ion travel through the field and become
electrostatically charged, resulting in adhesion
between the two sheets and the particleboard. With
this arrangement, the voltage differential between the
charging bars can be substantial. The sizeable voltages
cause higher levels of charge to be deposited on the
decorative sheets, which results in the highest level
of electrostatic adhesion. This method of charging
materials is generally used in the most difficult
pinning applications. Dual polarity BP-Series power
supplies are designed for applications like this.
Mounting Charging Bars
WARNING!
Fire Hazard
Do not install or operate equipment in close proximity to any flammable solvents or
flammable materials.
CAUTION! Electrical Shock Hazard
Only qualified service personnel are to perform installation tasks. Precaution should be
taken to shut down and lockout charging generator prior to service.
CAUTION! Electrical Shock Hazard
It is essential that the machine frame, and all metal parts in the vicinity, be grounded either
through well-grounded electrical conduit or by heavy copper wire connecting the frame
to a water pipe.
