trol system. Compared to a normal
stenter with heat-recovery system
this dryer saves an additional 30
per cent of energy.
The proven split-flow air circu-
lation system and BRÜCKNER’s
typical countered design has been
maintained in this concept. This en-
sures an absolutely homogeneous
air admittance to the fabric across
the complete length and width of
the machine. Since this line can be
provided with a support belt it is
perfectly suited for delicate knitted
fabric, too.
Supra-Flow BH is the first belt
dryer for spunlace nonwovens.
In the manufacturing of spunlace
nonwovens drum-type dryers are
in most cases used after water jet
bonding. BRÜCKNER’s new flow-
through belt-dryer Supra-Flow BH
sets new standards in the field of
spunlace nonwovens.
This belt dryer is characterized
by an unmatched temperature ac-
curacy across the fabric width. The
drying can be made very gentle
and with low temperatures since
the zone temperatures and the air
circulation intensity can be varied
every 1,5 m. In addition, the non-
wovens are dried on a transport
belt without any tensions or distor-
tions. This leads to a very smooth
hand and improved quality fea-
tures.
The new belt dryer can be used
without problems for large fabric
widths, high production speeds
and lightest fabric qualities. A par-
ticular feature is the unbeatable
energy efficiency of this new tech-
nology which was introduced by
BRÜCKNER in 2010.
Supra-Flow BX, the new dryer,
is used for the bonding of high-
loft nonwovens. Nonwovens with
a weight of up to 6000 g/m² and
an initial thickness of 300 mm can
be finished. Flow in the dryer can
take place from the bottom up or
from the top down, depending on
the process and the fabric type.
Also in this case the advantages
of the countered design are ap-
parent. The homogeneous air and
temperature distribution across the
complete fabric length and width
ensure a high-quality end prod-
uct. An optimum air control system
requires less electrical energy and
thus saves costs. The system is very
easily accessible for cleaning and
maintenance. To convince custom-
ers of the benefits of this system the
company will have within a short
time a pilot plant available for fab-
ric tests.
Techno-Line Coating represents
innovative line systems for func-
tionalizing and coating of textiles.
BRÜCKNER lines allow, among oth-
er things, direct coating on textile
webs and foils, reverse coating on
transfer paper, impregnation and
submerged coating as well as dry
and wet lamination of membranes
and textile webs. A particular high-
light is a new application unit for
the direct coating of bi-elastic knit-
ted fabric which is integrated in the
stenter entry. In addition, a new ap-
plication unit for coating of the low-
er side of the textile web has been
developed. Both units in combina-
tion allow a simultaneous coating
of the upper and lower side of the
textile web in one dryer passage.
Solvent coating units are required
for the production of a great variety
of technical materials. Glass mesh
fabric is, for example, coated with
resins to produce grinding discs.
Seat covers are often laminated
with coated membranes or foils to
ensure the breathability. And also
for the production of sailing cloth
or artificial leather made of PU a
solvent coating application is used.
BRÜCKNER lines provide for an
intelligent exhaust air system which
charges the exhaust air with sol-
vents up to the maximum accept-
able limits. Thus, enormous energy
savings can be achieved by reduc-
ing the exhaust air quantity. A sys-
tem for the monitoring and control
of the exhaust air burden provides
for failure-free operation and the
meeting of legal regulations.
