Abstract: A finish applicator mounting unit includes an apertured member having a plurality of apertures shaped to receive a corresponding plurality of finish applicator nozzles, and a locking mechanism that selectively obstructs the plurality of apertures such that when the corresponding plurality of finish applicator nozzles are received in the plurality of apertures, the finish applicator nozzles are selectively locked in the finish applicator mounting unit. The mounting unit preferably includes an alignment pin that ensures both proper alignment and proper insertion of the finish applicator nozzles. The finish applicator nozzles include a ceramic applicator head fictionally received in an elastic connector. A filament slot is configured to cooperate with the alignment pin to ensure the proper alignment and insertion of the nozzles. The nozzles operate more effectively and efficiently than conventional nozzles, and the mounting unit enables easy access to the nozzles for cleaning, repair and/or replacement.

Abstract: A cabled yarn untwister untwists cabled yarn to obtain yarn components. The cabled yarn untwister includes an untwister frame that is rotated by a motorized drive unit (e.g., a hand-held electric drill). The untwister frame is preferably substantially T-shaped and includes a connector leg forming the base of the T-shape and a cross-wise extending yarn attatchment arm. The yarn components are attached to swivels disposed at opposing ends of the yarn attachment arm after which the untwister frame is rotated by the motorized drive unit while maintaining the cabled yarn under tension. Rotation of the untwister frame, in turn, causes the opposing ends of the yarn attachment arm to move in a generally circular orbital path and thereby untwist the individual yarn components of the cabled yarn.
