A ContiRoll ® designed by Siempelkamp always guarantees long-term success. The
Siempelkamp service specialists contribute their part by maintaining or increasing
the productivity of a press even after many years of operation. After a recent
modernization, the 1989 ContiRoll ® of the wood-based panel manufacturer
FunderMax, Austria, is now operating with increased efficiency.
FunderMax, a well-known Austrian
wood-based panel manufacturer, is
operating two forming and press lines
including ContiRoll ® presses in neudörfl
near Vienna for the production of particleboard.
this location has an annual capacity
of approx. 500,000 m³ of particleboard.
In January 2011 siempelkamp received
the order for the modernization of the
older of both continuous forming and
press lines. the centerpiece is a 7’ x 23 m
ContiRoll ® press which started operating
in 1989. the scope of supply includes the
design, production, and assembly supervision
for the complete modernization
which was carried out between early
August and early september 2011.
A closer look at the details: A continuous
forming belt from the forming station to
the press infeed conveyor was installed as
part of the modernization. “thus, the
transfer points on the forming belt are
omitted. this helps the plant operator to
avoid damages on the surfaces of the
produced particleboard,” says Michael
Willemen, Manager sales for Modification
and Modernization at siempelkamp. the
pre-press was upgraded to today’s common
pressure and position control.
Upgrades in the infeed area: setting
the right course from the beginning!
numerous modernizations concentrated
on the press infeed area. Because the
complete press infeed area of the second
generation ContiRoll ® press was modified,
the press infeed conveyor and the existing
mat reject were adapted. the important
innovations at a glance: an infeed drum
support, new press infeed heads, four
additional press frames in the infeed
section as well as a 3.5 m long power hotplate
with integrated secondary heating
circuit.
“through these modifications the hotplate
length in the press infeed was extended.
the pressureless exposure time of the
product is decreased which in turn results
in increased capacity for our customer,”
explains Michael Willemen. Furthermore,
siempelkamp’s service staff installed belt
tracking cages of the latest design as well
as steel belt cleaning devices for the upper
and lower steel belts.
the existing mechanical product width
adjustment was replaced with a modern
position control via proportional valves. to
accomplish this, a completely new press
hydraulic system, including hydraulic unit,
functional beams with valve blocks and
the associated pipelines were supplied and
installed.
