Abstract
An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.
