HYPER COMPRESSING MACHINE FOR HIGH DENSITY WEBS AND BOARDS

** A new generation of non woven is now possible with this innovative machine, transforming a standard wadding in a hard and rigid panel, to be used for technical applications. Very high density could be reached with standard nonwoven lines **

The operating principle is a combination of two existing and well know processes:

calendering + thermobonding.

A calender could applies a very high pressure to the product, but for a reduced amount of time, while in thermobonding ovens the product could be heated for a considerable time, but at low pressure. The combination of high pressure + heat + time is what make unique this machine and his final production.

The material is pressed by two plane belts that convey it trough the heating system. Heating of the material is done by various hot plates in direct contact with the belts, warmed by forced oil circulation, placed on top and bottom. The hot plates warm up the belts that transfer the heat to the product, while it is alwasy compressed between the belts. Various couples of pressuring rollers, working on the belts, increase the compression of the material. The belt and rolls distances are adjustable, following the needed thickness.

Before being released, the product is cooled between the belts, so that it is completely stabilized.

Even with small amount of Bicomponent or PP fibres in the blending, the non woven could be esily compressed with low thickness, getting higher stiffness than in the conventional air trough ovens.

Not only compression: Lamination or smoothing of the product surfaces , are other applications of the machine.
