The fiber is pneumatically conveyed to the feeding section consisting of an volumetric feeder (01) where a fiber batt is evenly formed across the working width of the machine. The material proceeds through the opening section (02) and is fed to the forming chamber (03) where the combination of a series of distributing rollers and the vacuum below the perforated belt (04) at the bottom of the chamber guarantees an even distribution of the fibers and a perfectly horizontal stratification. Continuous weighing systems (05) and (06) installed before and after the forming chamber allow a perfect control of the density of the final product, ready for the following thermal or mechanical bonding section.
Working width: from 1000 to 4000 mm (other options available on request)
Production capacity up to 500 kg/h per meter wide
Product weight range: from 100 to over 3000 g/m2, depending on the material processed
Final product thickness up to 200 mm (other options available on request)
Fiber length range: from 1 to 60 mm (other options available on request)
Maximum density deviation: ± 5%
Fiber orientation: randomly distributed on horizontal layers
