Option 1: Charging Bar with a Grounded Surface
In
Figure 1
, the charging bar faces an empty core in a roll-to-
roll changeover application. The empty core is mounted on a
grounded metal shaft and a plastic film travels between the
charging bar and the empty core. The negative ions created by
the charging bar are driven toward the grounded metal shaft by
an electric field formed between them. The film blocks ion
travel through the field and becomes electrostatically charged,
resulting in adhesion between the film and roll.
In
Figure 2
, the charging bar
faces a production fixture that
moves beneath the charging
bar (alternatively the bar
could move over the fixture)
in an interleaving application
where paper or film is pinned to metal prior to cutting
and stacking. After the materials to be pinned together
are positioned on the fixture, it moves beneath the
charging bar. The negative ions created by the bar are
driven toward the grounded metal fixture by an electric
field formed between them. The top material blocks ion
travel through the field and becomes electrostatically
charged, resulting in adhesion between the two materials
and the fixture.

Option 2: Charging Bar with Static Neutralizing
Bar
In
Figure 3
, the charging bar faces an insulative film
while a static neutralizing bar faces an insulative sheet
of material on the opposite side (glass, plastic, light
particle-board, etc.). As the two materials to be pinned
together pass between the bars, the negative ions created
by the charging bar charge the film, while the static
neutralizing bar attempts to eliminate the apparent charge
on the sheet. This deposits a positive charge on the lower
sheet. The use of the static neutralizing bar dramatically
improves the electrostatic pinning adhesion between the
two materials.
