| description | Spunbonded nonwoven is made from continuous thermoplastic filaments emitted downwardly by a spinneret in a filament direction. A cooling chamber directly beneath the spinneret receives the filaments from the spinneret and cools the spun filaments with cooling air and has relative to a longitudinally extending machine direction a pair of longitudinal sides extending parallel to the machine direction and a pair of transverse sides extending substantially perpendicular to the machine direction between the longitudinal sides. Respective air-supply manifolds on the transverse sides feed cooling air therefrom into the cooling chamber. The cooling air is extracted from the cooling chamber at the longitudinal sides. A stretcher directly beneath the cooling chamber receives and elongates the cooled filaments, and a device deposits the stretched filaments as a band and conveys the band off in the machine direction. |
