Static producers are generally used to hold substrates together to
enable further processes to be carried out.
Positive and negative dc voltages up to 30 kv are applied either side of the substrates by bars, probes or sword type electrodes.
The induced dc current creates a voltage difference between the
substrates which causes the tacking effect. |
A typical application is the tacking of multi webs in the folding unit of a printing press, to ensure perfect folding and cutting at high speeds.

sword type
electrodes where
space is at a
premium |
Above is an
example using
area inductor
electrodes for
high level tacking
e.g. web edges |
 | Our latest system design
incorporates conductive
rollers to transmit the
charge from the inductor
bars to the sheets to be
tacked.
This system can be
installed in all types of folders. | | |
