ABSTRACT:
Process and apparatus for applying finish to yarn and confining finish are disclosed. The apparatus for applying finish features an applicator face which comprises the delivery area of a finish supply duct and the surface area of two primary arcs, one located on either side of the duct and curving in the general direction of yarn travel. The central angle subtended by each of the primary arcs ranges from about 2 to 9 degrees. The edge of each of the primary arcs remote from the duct terminates in a secondary arc which subtends a central angle of 30 to 60 degrees and with a radius length shorter than that of either primary arc. The apparatus for confining finish comprises a housing, plate and baffle(s). The housing substantially encloses a finish application device and has openings for yarn entrance and exit and for take-off of excess finish. The plate is mounted beneath the finish application device. The baffle(s) are disposed between the plate and the take-off opening. The plate and baffle(s) are oriented with respect to the housing such that any finish overflow and spray coming into contact therewith feed by gravity away from the traveling yarn to the take-off opening. The process comprises metering finish to an applicator face and simultaneously maintaining yarn in traveling contact with the entire length of the face and a portion of the edge thereof so that initial and last yarn-to-applicator contact is non-tangential to the applicator face.
