摘要:
An apparatus for making a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers has a row extending in a travel direction of two, three, or four spinning beams each emitting a multiplicity of multicomponent crimped continuous filaments with the filaments of each beam having a degree of crimp different from that of the filaments of each of the other beams. Respective extruders supply each beam with the components of the respective filaments and respective supply units feed each of the extruders with the respective components. The rate at which the components are supplied to the extruders is adjusted for varying the proportions of the components in each filament. A conveyor extends in the direction below the beams and receives the filaments as respective layers from the respective beams.
