Abstract: Disclosed is a melt-spinning process of the type wherein molten polymer is extruded downwardly through a filter pack and through an annular array of holes of a spinneret to form a circularly arranged group of filaments. Quench gas is delivered downwardly through said pack and spinneret coaxially relative to said row of holes and the redirected and discharged outwardly through the group of filaments. A finish substance is sprayed onto the filaments, and the filaments are gathered and redirected at a guide. The finish spraying comprises the steps of conducting the finish substance through the pack and through the spinneret internally of the flow of quench gas, and discharging the finish substance outwardly from within the group of filaments at a level below the discharge of quench gas.
