Abstract
A method of making a spunbond fleece from continuous filaments wherein at least some of the filaments produced have natural crimp. The filaments are deposited in the deposition station of a conveyor creating a filament mass and the conveyor transports the filament mass toward a consolidating device. A gas stream is produced that flows along the upper surface of the filament mass in the travel direction of the filament mass.
