Since 2009, WEIG-Karton has
worked closely with Procemex to improve the
optical process monitoring on their folding
box board line. Initially, a fully integrated
web monitoring and inspection system was
installed, and in 2013 the potential for product
quality improvements was further increased
when resolution was doubled by updating
cameras to the latest FullHD technology.
KM6, the gypsum liner board machine,
was fitted with a portable high speed camera
system. Four FullHD pinhole cameras were
installed at the wet end to improve troubleshooting accuracy, which was successful in
helping operators focus their troubleshooting
in the right areas of the wet end. This success
was followed by further collaboration between
SEAMLESS INSPECTION ON
The team's groundbreaking idea was
to monitor the wire with a pinhole web
inspection beam. Procemex had previously used camera beams to inspect pick-up
areas with promising results, and they had
developed a pinhole beam technology for
full-width web monitoring and inspecting
extreme areas of paper machines. The technology guarantees seamless inspection without any disturbances caused by conventional
cleaning mechanisms, such as wipers.
Thanks to the new technology, web
inspection beams can be used in even the
most demanding areas of paper and board
This was the preferred beam technology
for the exit press section and the sizing press
entry. The same image resolution could be
used in all three beam positions in order to
Single pinhole cameras were installed
alongside the beams on the headbox of the
KM6. Now defects and their root causes
can be identified quickly through a process

major improvement in process monitoring
