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.
