05 | 2011 EVOjet™ Cuts resin costs No resin spots on the board caused by the EVOjet™ No extended maintenance needed page 2

05 | 2011 Resin injection zone Resin injection 3 4 EVOjet™ fiber flow is very well disintegrated The spike rollers disintegrates the fiber, minimizes fiber balls & flocculation Exposed fiber flow surface (A x B x C = D) A=Effective resin distribution width, meter B=Number of surfaces to be sprayed C=Air speed, m/s D=Available fiber flow, m2/s (calculation based on 24 t/h fiber throughput) Fiber speed 40 m/s 2 x 4 x 40 = 320 m2/s page 3
