Abstract
A finish applicator includes one or more applicator plates stacked adjacent a guide plate and preferably between a pair of guide plates, at least one of the guide plates having an opening formed therein forming a yarn passageway and positioning the yarn in close proximity to, or in contact with an edge of the applicator plate. Alternatively, the guide plate and applicator plate may each have one or more openings formed therein which in registry form a yarn passageway when the plates are stacked. The opening in the guide plates may define retaining arms which maintain the yarn to be treated in close proximity to, or in contact with a treatment edge of each applicator plate.

An apparatus for applying treatment fluid to yarn comprising:
- at least one guide plate having an elongate opening formed therein;
- at least one applicator plate stacked sealingly adjacent said guide plate, said opening in said guide plate forming a passageway through which multifilamentary yarn can pass and positioning the multifilamentary yarn in close proximity to an elongated fluid applicating edge of said applicator plate;
- said opening and said edge defining means to spread the multifilamentary yarn and apply fluid approximately evenly to the spread yarn;
- and
- supply means for providing treatment fluid to said edge of said applicator plate.
An apparatus for applying treatment fluid to yarn comprising:
- at least one guide plate having an elongate opening formed therein;
- at least one applicator plate stacked sealingly adjacent said guide plate and having an opening formed therein, said openings in said guide plate and said applicator plate communicating to form a passageway through which multifilamentary yarn can pass so as to be spread along an elongate fluid treatment edge of said opening in said applicator plate to cause each filament to receive approximately even fluid application;
- and
- supply means for providing treatment fluid to said edge of said opening in said applicator plate.
An apparatus for applying treatment fluid to yarn comprising:
- at least one guide plate having an elongate opening formed therein;
- at least one applicator plate stacked adjacent said guide plate, said opening in said guide plate forming a passageway through which multifilamentary yarn can pass to an elongated fluid treatment edge of said applicator plate thereby defining means for spreading and guide multifilamentary yarn to said elongate edge where each filament receives approximately even fluid application;
- and
- supply means for providing treatment fluid to said edge of said applicator plate.
