Percussion oven

The Sicam double belt or single belt impingement ventilation ovens are suitable for the thermobonding or the thermosetting of nonwovens which support an high speed ventilation treatment like the needle punched webs. The Sicam know how permits to foresee this oven with different kinds of ventilation according to the different products.
For the needle punched nonwoven the ventilation can be at high speed on the both sides with air through effect. For not permeable materials is suitable an impingement ventilation on the both sides without air through and with air recovery on the same side. For the drying of one surface of a nonwoven after coating or impregnation is suitable a one side impingement ventilation.

Sicam has a particular care in the choice of the conveyor belts according to the production request of the customers, as the conveyor belt is a strategic component for the final quality of the nonwoven. The top conveyor is magnetically supported and in this case conveyor of course are metallic and chosen by Sicam among many kind of conveyors in order to find the best compromise between the final surface finishing of the non woven and the optimization of the maintenance and cleaning operation.

In addition we find the construction Sicam philosophy without sliding elements. this solution make possible an easy access and to inspect inside the oven reducing the maintenance time and costs.

The construction philosophy by modular section of 2250 mm of length, used by Sicam since many years in its production range, makes easy the transport operation all over the world allowing a simple load in containers if preassembled machinery section.
