It is more than 20 years that Bombi Meccanica developed his double belt press to be used in various applications.
Recently we have upgraded our model to meet specific requests into pads making for automotive industries.
These pads are generally made by a blend of Kenaf or Hemp fiber and PP, formed with air lay system and needle punched. With a weight of 1500-1800 gsm , they result with a thickness of 15-18mm around.
To form such web with a 3d press means a big energy consumption + time wasting as the heat must penetrate into a 15-18mm thick insulating product.
The solution is to use a double belt press just after the needling process to reduce the thickness of the felt till 3-5mm. This make a hard and stiff pad, that could be very easily warmed before the 3D forming, saving energy, time and getting a more precise product as it is much more dimensionally stable.
The machine uses a series of large hot calenders to press down the web and hot plated for heating till the center of the machine where a double calender block the felt definitely and push it into the cooling area. The cooling comes with cold calenders and cold plates, in a similar way of the heated zone. The big rolls size and double calender assure optimum thickness control on the final product.

Application :Compressing of webs made with cellulose + Bico, used under wooden floors, to prevent noise and to insulate from cement floors.
Compressing of wood-fibers with PP. This is used to produce medium density wood boards, without the use of an extremely expensive wood production line. Lamination of two or more felts without any chemicals, just using the fibers.
Equipping the machine with our powder\particles scattering unit, it is possibile to transform any of your waste containing fusible fibers or fusible material into rigid boards that can then be used in various applications. No need to dump your waste or to buy a nonwoven line to transform it into a usable or sellable product: just grind it into small pieces and press with the continuous press. There are endless possibilities for any kind of waste, however small the quantities are.
Compressing of polyester thermobonded webs, in blend with bico, to produce sound insulation boards.
Laminating of shoddy felt with a polyethylen foil, to produce a protective felt for painting.

For the production of roof insulation panels for houses or partition walls for offices or sound insulation pads under the wooden.
For automotive elements, with a blend of fiberglass and PP\Bico.
To re-use shredded waste carpet and turn it into rigid boards, finding new life from waste.
To produce hard panels that can be secondly molded with a 3D press.
Can be used in any possible way to transform a low cost web\pad\waste into an high added value technical end-product.
For lamination of multiple layers of felts or composite materials, or Melt one layer of polyethylen film on the web.
For melting and compress the scattered powder alone, or on top of felt\wadding, or in sandwich between 2 felts.
Can be used with bonded webs (needled or thermobonded), but with loose fibers too.
To produce wood-like panels out of web made with natural (wood, kenaf, sisal) fibers.
To produce marble-like panels out of waste fibers\particles. The panels could be hard as stone.
To recover powder or particles coming from other industrial processes (when containing or blended with melting components like PP)
For the realization of water-proof webs

Production site, located in any place of the world, is connected via internet with our systems in Italy. Customer is assisted in real time for any kind of problems, modifications, future adding without the need to send locally a technician.
