摘要:
An apparatus for making nonwoven from continuous filaments has a spinner for spinning the filaments, a cooler for cooling the spun filaments, and a mesh belt that moves in a generally horizontal travel direction and that passes through a deposition location where the spun and cooled filaments are deposited on the mesh belt to form thereon a nonwoven web. A nose roller defines a deflection zone over which the mesh belt is deflected from its travel direction downstream of the deposition location. At least one lift roller above the mesh belt downstream of the deposition location separates the nonwoven web from the mesh belt at a separation location at a first spacing upstream from the deflection zone of the nose roller. A treatment device for the nonwoven web is provided downstream of the mesh belt in the travel direction and receiving the nonwoven web from the lift roller.
