Lap Formair is based on a new aerodynamic fibre batt formation system, ready for subsequent needle punching or thermobonding processes, giving the final product a fibre density which is perfectly even both longitudinally and across the whole machine width. This machine’s extraordinary performance are especially characterised by the possibility of processing any type of material, both fibrous and non-fibrous, thus guaranteeing a perfectly even density also when manufacturing low weight final products (down to 100 g/m2 weight).
Strenghts
- reduced production costs
- reduced investment costs
- reduced space occupation and energy consumptions
- possibility of processing non cardable fibres and materials
- extreme productive versatility in terms of processable raw materials and type of manufactured final products
- high production quality also when manufacturing light weight products(down to 100 g/m2)
Process flow
The fiber is pneumatically conveyed to the feeding section, which consists of a volumetric feeder (01) that forms a fiber mat uniformly distributed across the working width. The material then passes through an opening section (02), which feeds it into the forming chamber (03). There, the combined action of a series of distributing cylinders and the suction pressure through the perforated belt (04) at the bottom of the chamber ensures a uniform material distribution and a perfectly horizontal fiber stratification. Continuous weighing systems (05) and (06), installed respectively upstream and downstream of the forming chamber, guarantee precise control on the product weight at the outlet, preparing it for the next thermal or mechanical bonding steps.
