METHOD AND APPARATUS FOR PRECIPITATING SOLVENT OUT OF THE PROCESS AIR IN SPUNBOND PRODUCTION

摘要

The invention relates to an apparatus for laying filaments (3) to form a spunbond (8), dehumidifying the spunbond (8) and extracting the process air laden with solvent and coagulant, comprising a conveyor apparatus (7) for transporting the spunbond (8) in a transport device, the conveying device (7) having a support surface (6) for the filament (3), the conveying device (7) being permeable to gases and liquids at least in the region of the support surface (6), and a primary dehumidifying apparatus (9) being provided below the support surface (6) of the conveyor device (7), and/or at least one upper extraction apparatus (10, 11) is arranged after and/or alongside the support surface (6).
