Beschreibung
Zusammenfassung:	A device for laying down filaments (3) into a spundbond fabric (8), dehumidifying the spundbond fabric (8) and sucking off the process air loaded with solvents and coagulants, including a conveyor device (7) for transporting the spundbond fabric (8) in a transport direction, wherein the conveyor device (7) has a deposition surface (6) for the filament (3), wherein the conveyor device (7) at least in the region of the deposition surface (6) is permeable for gases and liquids, wherein underneath the deposition surface (6) of the conveyor device (7) there is provided a primary dehumidifying device (9), wherein there is arranged at least one upper suction device (10, 11) upstream and/or downstream and/or laterally of the deposition surface (6).
