A nonwoven web is made by first depositing fibers as a nonwoven web in a deposition area, then conveying the web away from the deposition area in a web-travel direction, preconsolidating the web in the path, and passing the preconsolidated web between a pair of rollers that compress and final consolidate the preconsolidated web, One of the rollers is separated from the web such that final consolidation of the web at a starting level is stopped and at the same time or immediately beforehand upstream preconsolidation of the web increased. After separating the one roller from the web, another roller is engaged with the web at the consolidation station and then final consolidation is recommenced, whereupon upstream preconsolidation of the web is reduced back to the starting level.

Nonwoven web and method of making same

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.

Making spunbond from continuous filaments

An apparatus for making spunbonded nonwoven from continuous thermoplastic filaments has a spinneret for downwardly emitting the continuous filaments in a filament direction, a cooling chamber directly beneath the spinneret for receiving the filaments from the spinneret and cooling the spun filaments with cooling air and having 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.
