TopCon® LP Double Belt Oven

Density from 6 - 80 kg/m³

The TopCon^® Double Belt Oven, the line for Nonwoven Bonding by hot air treatment to produce high loft Nonwoven as well as compacted Nonwoven.

Thermally bonded Nonwoven can be used for such purposes as upholstery, interlinings, mattresses, moldable Nonwoven (moulding), sun blinds, insulating material and cosmetic pads.

The web is always a mixture of the standard fibre and a low melt fibre. As melt fibre, mostly special bicomponent fibres are used and (or) polypropylene fibres.

The thermal fibre treatment is done by air-through flow. The hot air circulates in a closed system, the web is transferred through between two conveyor belts and because of this, the whole air quantity is forced to penetrate the web and is available as heat transmitter.

The continuous web is placed immediately at the inlet of the oven section and is calibrated down to the requested thickness.

From the start of the heating up-process until the end of the cooling down-process, the web remains in the same position and the structure of one fibre to another is maintained (thermo-bonding process equals (=) heating up and cooling down).

This is possible by using heat resistant synthetic conveyors, which consume a minimum of heat energy, and can pass through the heating and cooling sections without interruption due to their characteristics.

The upper conveyor belt is adjustable in height and allows, on one hand, to have air flow direction from bottom to top without touching the upper air nozzles and, on the other hand, to densify the web by reducing the distance between the two conveyors. Therefore the wide range of density from 6 to 80 kg/m³ is reachable.

There is a choice of the airflow direction every metre; this makes the line very universal and flexible, you can influence the product surface quality directly.

Gas is usually used for heating up the air.
