The recently commissioned Brückner coat-
ing line for tufting carpets is one of the biggest
of its kind with a total length of 170 m. The
production capacity extends to a maximum of
20 million m² per year depending on the type
of fabric and the process. With this line proc-
esses like pre-spread coating for pile integration,
secondary-back laminating with flat fabric or
nonwovens and foam coating with flat foam or
embossed foam are possible.
The drying process takes place in 23 DUO-
THERM drying zones in total. This dryer type
proved to be excellent for coating in the field of
carpets. The gas-heated dryer is operated with a
temperature splitting for the thermal treatment of
the pile and the coating side. This ensures a high
drying capacity with an operation mode which is
very gentle for the pile.
Photo 2 shows a cross-section of the DUO-
THERM dryer. The separated air circulation of
upper and lower air allows temperature differ-
ences of up to 60°C. With the Venturi mixing
system for gas heating a perfect temperature
distribution is achieved. The use of inverter-
controlled circulating air fan motors allows a fast
reaction on different types of fabric. This pre-
vents pile deformations. The central Siemens S7
control system ensures a perfect reproducibility
of the production data.
The different coatings are applied as foamed
latex mixtures. For this purpose the newly devel-
oped Brückner carpet application unit is used.

dams (with motorized control via edge sensors)
and motorized traversing paste distribution. The
chromium plated squeegee is water-cooled to
prevent adhesion of the latex.
The motorized nip adjustment via spindles is
made on both sides and is monitored by angle en-
coders. Normally a parallel adjustment is made,
and also corrections on both sides are possible.
The squeegee can be decharged pneumatically
via a fourfold joint. Due to the rotation around
the joint, the squeegee roller gives way not only
Dinarsu Imalat ve Ticaret T.A.Ş. established in 1955 in Istanbul for production
of yarn and blankets, began producing tufting carpets and nonwoven carpets. It
turns out high-quality products to remain competitive in the international market.
In the selection of machines and technologies the group concentrates exclusively
on European or American peak technology beginning with the tufting machine via
advanced Chromojet printing lines until coating and finishing lines.
