Abstract
Disclosed is a melt-spinning process of the type wherein molten polymer is extruded downwardly through a fiber pack and through coaxial circular rows of holes of a spinneret to form a circularly arranged group of filaments. Quench gas is directed across the filaments emerging from the spinneret, and the cooled filaments are gathered and redirected at a guide, which may be stationary or rotating. The quench gas is delivered by a conduit extending downwardly through the pack and spinneret coaxially relative to the rows of holes and then redirected and discharged laterally outwardly through the group of filaments above the guide.
