Abstract (en)
[origin: WO2018055181A1] The invention relates to an aerodynamic nonwoven forming device (2) for a fibrous nonwoven (10), wherein the nonwoven forming device (2) has a discharge region (6) for fibers, in which the fibrous nonwoven (10) is aerodynamically formed. The nonwoven forming device (2) is incorporated in the discharge region (6) in a furnace (4), wherein the nonwoven forming device (2) has a fiber support (5) which emits a fiber stream (12) in the discharge region (6) into a free area (31) within the furnace (4), wherein the fiber support (5) spins off the fiber stream (12) on a detachment area (22) into the free area (31) in free flight.
