ABSTRACT:
A yarn finish applicator in which finish is metered to a slot running from top to bottom of the applicator. The configuration of the body of the applicator and its slot provides an edge at the exit end of the applicator and a slot that is slightly wider at the location at which finish is metered to the slot than at exit of the slot. Two rods are located just below the exit edge of the applicator to collect and drain to a receiver any drops of excess finish which form at the exit edge of the applicator when the threadline is not running.
