Abstract
A stabilized filament drawing device for a meltspinning apparatus and a meltspinning apparatus including the stabilized filament drawing device. The stabilized filament drawing device applies a high-velocity flow of air to attenuate the filaments, which are discharged from a device outlet in a discharge direction. The filament drawing device includes multiple inclined guides adjacent to the outlet that cause the filaments and high-velocity flow of air to deviate from the discharge direction. Each of the guides has a major surface that is angled relative to a common plane containing the discharge direction and a cross-machine direction of the device outlet of the filament drawing device. The guides are oriented such that the major surface is also inclined relative to the discharge direction.

Abstract
A spunbonding apparatus capable of producing multicomponent spunbond filaments. The spunbonding apparatus includes a spunbonding apparatus comprises a spinneret discharging multicomponent filaments and a filament-drawing device applying a first force that is effective to attenuate the filaments. A force applicator stationed between the spinneret and the filament-drawing device is operative for applying a second force to the filaments that promotes filament splitting. Splitting may occur before the filaments enter the filament-drawing device, within the filament-drawing device, and/or after discharge from the filament-drawing device.

Abstract
A distribution manifold for transferring a balanced air stream to an extrusion die of a meltspinning apparatus, meltspinning apparatus including the distribution manifold, and methods of operating a meltspinning apparatus. The distribution manifold comprises a body member having a cavity, an inlet coupling the cavity with the air supply, and a plurality of outlet passages coupling the cavity with the extrusion die. A plurality of metering elements are disposed within the cavity between the inlet and the plurality of outlet passages to restrict the flow of air through gaps formed between adjacent pairs of the metering elements.
