Abstract
An apparatus for making a nonwoven fabric from thermoplastic plastic filaments has an air permeable deposit conveyor having a horizontal face displaceable in a horizontal travel direction and a spinneret above the conveyor for spinning the filaments and depositing the spun filaments on the deposit conveyor in a deposit area of the conveyor as a nonwoven web for conveyance in the travel direction. An extractor beneath the conveyor draws air or process air through the deposit conveyor in the deposit area in a main extraction area below the deposit conveyor and is delimited by, relative to the travel direction, upstream and downstream suction partitions. One of the partitions has an upper edge set at a predetermined vertical spacing below the conveyor equal to between 10 mm and 250 mm.
