Flocking Devices - MHM Synchroprint X-Type plus Operating Instructions Manual

7.10.1. Flocking Devices

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 the
flocking device's manufacturer and observe all safety regulations. Any
noncompliance may endanger people and result in material damage to
machines.
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.
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.
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".
