Flocking Devices
During the flocking process high voltage is
used to generate a magnetic field, which
aligns the flock fibers and transfers them
onto the substrate. Installation and
selection/control are similar to those of
intermediate driers.
Therefore, the following protective equipment is prescribed for flocking devices:
1.
Optimal grounding of all machine components:
All machine parts must be connected using adequately dimensioned cables. In
addition to the earth connection via the main lead, the machine must also be
connected to the building’s grounding.
2.
Installation of a metal drier socket.
3.
Use of a signal cable with good EMC- characteristics (07-0-0-0226-0).
4.
Shielding of the sensor cable through a screening braiding (30-1-1-0006-0).
5.
Installation of screening plates in front of the motion trackers (02-1-6-0024-0).
6.
Attenuation of drier as well as position signals in the squeegee/print arm by
means of ferrites (30-1-1-0005-0, also known as suppressor chokes).
Points 2-6 must be applied to all flocking stations as well as both adjacent stations. A
set with all needed parts for one print station can be ordered with part number 20-0-
0-9160-0. Please find
detailed instructions in the file “package of measures for the use
of flocking devices.pdf”.
In case of any spark-over due to the high voltages applied, the
electromagnetic interference arising from them may affect, or in
extreme cases even destroy, the printing machine and other
components.
The high voltage of several thousand volts required for the flocking
process represents a great threat for man and machine. That’s why
only specially qualified workers familiar with all potential risks are
allowed to operate flocking devices. Before starting the machine,
please read the manual of t
he flocking device’s manufacturer and
observe all safety regulations. Any noncompliance may endanger
people and result in material damage to machines.
