CONTINOUS PRESS

The Sicam double conveyor continous press is suitable for the lamination, the surface finishing and the compression and so density increasing of nonwovens.
Sicam has developed a working principle based on a combination of heat and pressure. The Sicam double conveyor press is able to obtain a perfect smoothing effect on the surface, is able to laminate more materials ( also not permeable) by melting the fibers or with the help of powder or liquid adhesives, and is able to increase the material density in the nonwoven mixed with PP or Bico PES.
Sicam reaches the above results thanking to a machine which provides for the passage of the material in pressure between two conveyor belts in glass / Teflon between fist hot plates and then cool plates.
To produce different thickness between the heating zone and the cooling zone couples of calendar rolls are placed.

CALENDERS

The Sicam hot calendar can be supplied with two or three rolls, driven dried by a cardanic shaft system and independent motors and can be heated by:

• direct electric heating
• diathermic oil heated by electric resistance or gas boiler

In the calenders with oil heating system, Sicam uses high flow pumps which allow to keep at low level the temperature delta between the entrance and the exit of the oil from the rolls, to obtain a perfect temperature uniformity on the surface of the roll to obtain a top of quality nonvowen.

This temperature uniformity is obtained also thanking to the high speed oil circulation inside the roll in proper channels.
According to the company philosophy, Sicam carefully chooses the materials and the thermic treatment of the rolls of the machine according to the request of the technological process.
The rolls are built in a special steel which then after thermical treatment reach a very high hardness not only on the surface , but also in the deep thickness.
